Subject: Welcome to APOLLO
∂05-Jun-81 2215 DUFFEY at MIT-AI (Roger D. Duffey, II) Welcome to APOLLO
Date: 6 JUN 1981 0115-EDT
From: DUFFEY at MIT-AI (Roger D. Duffey, II)
To: New APOLLO Subscribers
Hello,
Welcome to the APOLLO mailing list. APOLLO discusses personal
work station computers, like the APOLLO work station computer,
BBN's Jericho, the Three Rivers Corporation PERC, or the newly
announced Xerox STAR. APOLLO provides a way for interested
members of the ARPAnet community to discuss what is wrong with
these machines, compare notes on work in progress, and share
useful insights about these kinds of systems. The list is
managed by Hank Dreifus <Dreifus at WHARTON>.
APOLLO is currently discussing initial reactions to the Xerox
Star Workstation. Sandor Schoichet <SROSS at MIT-XX> has been
conducting an informal survey about the Star. The current
results are available in the file DUFFEY;APOLLO STARMS on MIT-AI

Hank Dreifus <Dreifus at WHARTON> is conducting an initial
survey about the personal workstations people on this list
are using and/or developing. He would like to send him a
brief message describing the OA machine you use and why
(or why not). He will collect the responses and distribute
a final summary to the list.
A complete record of the APOLLO discussions will be maintained
in the file AI:DUFFEY;APOLLO ARCHIV. The archive is small now
because APOLLO is only a few days old. However, this will
change rapidly.
Comments in the ongoing discussions should be addressed to
APOLLO@MIT-AI. Administrative requests (eg. a message asking
to add someone to the mailing list) or questions about the
goals of this list should be addressed to APOLLO-REQUEST@MIT-AI.
Lastly, welcome to APOLLO. I trust you will enjoy being part of
these discussions.

∂11-Jun-81 0714 DREIFU at WHARTON-10 (Henry Dreifus) Themes for discussion
Date: 11 Jun 1981 (Thursday) 0915-EDT
From: DREIFU at WHARTON-10 (Henry Dreifus)
To: APOLLO at MIT-AI
Some of the topics I would like to see discussed by this discussion
list are:
o Definition of a personal workstation.
o The IDEAL personal workstation.
o Technical review of all participating machines
where some accurate knowledge of the machine
can be presented.
o The introduction of personal workstations into large
business. The question of operational logistics,
transferring an application to a small machine.
o Is the right answer to make the small workstation
look like a very slow version of a large mainframe?
o Example applications.
o Trade offs in networking the workstations. Performance
weighed against cost and overhead.
o Some of the plans for introducing workstations in
operational areas.
o End user(s) of workstations, the application skewed
machines.
o User interfaces, factors.
------------------------------
There are but a few ideas. However one caveat. Facts are better
than Flames. Please no flaming, that is the one thing this list
is better off without.

∂11-Jun-81 0735 DREIFU at WHARTON-10 (Henry Dreifus) Preliminary results from the personal workstations survey
Date: 11 Jun 1981 (Thursday) 0920-EDT
From: DREIFU at WHARTON-10 (Henry Dreifus)
To: APOLLO at MIT-AI
Below is a condensed version of the various systems that people
have made an attempt to respond to. The interesting point(s)
that I have noticed are:
o Everyone's view of PersOnal Workstations is different.
o The machine(s) selected are wide ranged and apparently
well suited for each application chosen.
o There is no wrong Personal Woristation machine.
o The technology of Personal Workstations is not well
established as of yet.
o There is a demonstrated need for this technology,
it appears to be one year away fRom general use.
o Most have:
Large address space (or VM).
Networking capabilities.
Very good display hardware.
Large local storage capacity.
Micro-processor based.
Contain an external locator type input device.
o Most are missing:
Software tools to round out system.
Market recognition.
Gateway access, no gateway specifications.
Too many parts, development schedules are
full, revision schedules are bare.
Consistency. This is a result of different
definitions of what a personal workstation
is supposed to be.
------------------------------
Below is a summary of the survey responses. Eventually, each
machine will be examined in greater detail. The intention is
to educate ourselves about personal workstations. They sound
neat, but what they are under the surface is still a hot topic.

Most of the comments on the Xerox Star that have appearred in the paper say
something like "very nice...for half the price". VERY few companies have
computer capitalization that exceeds $10,000 per person. That's roughly
what it is at DEC (internal transfer cost), and the average outside company
would have to spend a lot more to reach the same level, which I consider
just adequate (terminal at home, one at work, access to several group
machines). The comments that I have heard from people in marketing are
that they don't think that large numbers of the Star will be sold to peons,
but rather to management types, who can use it as a status symbol.
So one requirement of a personal workstation that you are going to give
to everybody, including the secretaries, is a price of less than $10,000
including overhead from network, printer, file servers, etc. Also including
software.

The 820 (or Worm) is a 64k Z80 based machine that (at 3k) has a
keyboard, display, two mini-floppies, and can run either CP/M or
a Xerox hacked over Wordstar (this from the local representative).
The only current Ethernet capability is through a RS232 interface
(which means that an Apple or a Osborne has the same capability).
Xerox will have some sort of a real Ethernet available eventually.
According the the San Jose News of last night, the 820 has no
graphics capability. The main thing this @i[appears] to have going
for it is the Xerox name--many companies would rather deal with a
Xerox or an IBM than an Apple or a Radio Shack or a ...
The above is based on information gleaned from talking to various Xerox
people and is no doubt incomplete. I imagine there are Xeroxers on
this mailing list. Perhaps they can fill us in more.

Hopefully, Xerox will provide the software for the 820 to speak with Star
systems. That is where the 820 could have the advantage over the Apple
or Osbourne machines. I think that a lot of people who would like to
go into office automation are cringing at the price of the Star (when they
think of all the people that they would want on their office network).
If the 820 provides a thoughtfully designed subset of Star capabilities
(and I don't know whether it will or not) at a fraction of the price
it could be a wonderful bootstrapping mechanism for getting Ethernet
based systems into the offices. And you can always unplug the 820
and plug in a Star at a later date (perhaps allowing the employees
to take them home for telecommuting purposes).

I think your argument is a little incomplete.
Suppose I make you the following deal: if you give me $10,000 today, I
will give you at least $5,000 every year for the next 5 years. I
think you will accept my deal, right?
Ok, now let's look at Star and suppose I can prove to you that it
makes me 10% more effective (this is hard to prove) or that it saves
me 10% of my time. My time actually costs the company $60,000 a year.
And I am but a lowly engineer making under $30K/year. So if the
if I do my work 10% faster, the company in some way, "saves"
$6,000/yr. (the savings could be in hiring less engineers or by
getting more work done per unit time or by getting the job done more
effectively).
In fact, the Booz-Allen study on the potential of office
automation (a very thorough case study of over 40 companies) concluded
the AVERAGE ROI on OA equipment was 86% annually and could be over
200% in some companies.
I think it is foolish to measure a system on cost. You measure on
price/performance or ROI. If Xerox can prove a high ROI, they will win.
I must work for one of those "VERY few" companies who spend over
$10,000 on computer equipment for engineers. It costs us $60,000 to
provide a computer port into our Data General Eclipse.

While your fundamental argument is correct, you neglected two
important points.
First, the $10K (or whatever) is not free. At today's rates,
$10K capital investment costs the company 20% interest, either directly
because they had to borrow it, or indirectly, because they don't have
it to invest elsewhere. So your increase in productivity would have to
be at least 20% to break even.
Second, as someone else has pointed out, no one knows how to quantify
the increase (if any) in productivity from something like a star, especially
vis a vis similar software running on less flashy hardware. This makes
it impossible to "prove" any increase in productivity.

From: Brian P. Lloyd <LLOYD at MIT-AI>
To: APOLLO at MIT-AI
Regardless of the arguments for and against the economic value of the
Personal Workstation (PW), the numbers are beginning to tell. I work
for Alanthus Data Communications and we market the Convergent
Technologies system to end users. Our marketing strategy is to point
out how the system provides OA, communications, and user
programmability in one box.
The response is overwhelming! The average configuration seems to be
going out at about $20,000 including software. Granted, at this point
in time people are buying development systems, but the availablity of
OA software (WP, mail, etc.) has been a driving point in almost every
sale.
Obviously people believe in the PW concept and the market is still
growing. Since people rarely exhibit rational behavior (except in a
negative [fiscal] sense), I don't expect rational decisions either way
on the subject. We all realize that OA and PWs are coming and noone
is going to stop it.
Since we all tend to be in areas of development for OA products, let
us now discuss what the needs of the user really are. Perhaps we can
decide what Office Automation and Personal Workstation really means.

From: LYNCH at USC-ISIB
To: Apollo at MIT-AI
The Star is almost useless to any of us who are doing computer
science R&D unless we can program it as we see fit. The applications
that Xerox has seen fit to release at this time are indeed quite nice
but do not justify the cost ($20K with software if you buy 50 or more
of them in a year's time -- they give a nice discount for volume
buys (about 25% off)). We asked Xerox to include Mesa.
They said OK. They have not yet quoted a price to us however.
We also asked for the microcode. Thye said Not at this time.
The Mesa release was contigent upon us buying a lot of them
(like 50-100). They are still confused about where their marketplace
is. If commerical orders do not flow in rapidly in the next
few months then they might be much more interested in
turning it into a "programmer's workstation" that would suit us.
WEe have also asked them to include much more memory on the Star.
They admit it can be done but that they are trying to build Even
smaller confiturations of it (it currently comes with 384 MB).

As I understand it, the Star comes with a somewhat low-power programming
language called CUSP. This is the only programming facility available to
the user. Rumor has it (and it would not surprise me) that there is an
extensive Mesa development system that could be run on the Star, but is
destined to never leave the hallowed halls of Xerox. (If I am wrong
on any of this I will cheerfully accept correct information from our
friends at Xerox who are reading this)
Apparently the reasoning behind this involves consistancy in system
software. If you don't give the users (who aren't supposed to be
programmers to begin with) access to the system programming language,
and armor-plate the language that you do give them, they can't
do themselves or the system any harm. Also, if you want a new
system application, you must ask Xerox to make it foR you. Thus
it will be wpitten properly (I am not being sarcastic here. There
is a lot to be said for this approach when your target market is
composed of non-programmers). Xerox doesn't want to find themselves
in the position of supporting outside software, because outsiders
don't have the information and the methodology to write that
software in a consistant manner with the rest of the Star system.

The major problem we have encountered at ISI is not the hardware costs, but
unwillingness of Xerox to supply us with the facilities to write our own
system software. The eventual availability of the Mesa language has been
discussed, but we need all the system software in oRder to configure the
system to be useful for our applications.
Another consideration iq the interjet protocols which are (as I am led to
believe) currently not supported.

Subject: Acquiring personal computers

Date: 13 June 1981 1534-EDT (Saturday)
From: Sam.Harbison at CMU-10A

Message-Id: <13Jun81 153417 SH01@CMU-10A>
There's been a lot of discussion about the pro's and con's of various personal
computers/personal workstations. Let me give a brief summary of some decisions
taken at CMU.
About two years ago, the CS department decided that our long-term computing
needs would be best met by a network of personal computers in offices, and
plans were made to embark on a research project (Spice) that would give us by
1985 the kind of software necessary for such an facility (including Lisp and
Ada programming environments, document production environments, and multi-media
communication). We thought that it would be 1985 before personal computers
appeared with the right power and cost. Because we did not want to do any
hardware design, we began to canvas manufacturers to see 1) what was available
now to start with, and 2) what might be available in 1985.
The machines close enough to what we wanted to act as a prototype were Perqs,
Apollos, Lisp Machines, Nu Machines, and Xerox D-machines (Dolphin, Dorado, and
the Star computer). Our principal criteria were that the machine had to have
all the basic features of a 'real' machine (display, net, etc.) and be flexible
enough to allow us to develop software for the 1985 machines now. Furthermore,
it was important that we be able to distribute our software to other people.
To make a long story short, Apollos and Nus did not have the writable
microstore that we considered critical, and their microprocessors did not seem
to be able to support the kind of multiprogramming we wanted. Lisp Machines
were too expensive and production (then) uncertain. Xerox and their machines
were philosophically close to us, but the Dolphin/Dorado were not commercial
products, and Xerox would not commit to releasing Mesa, meaning that we might
find it difficult to distribute a system built in Mesa. We finally chose to
begin with Perqs, which on paper are at least equal in performance to any of
the others except the Dorado and Lisp Machine. (And which can be
microprogrammed to be very much like the machine we really want, except for
performance.) The Star's advantage quoted by others is, I think, due to
software refinement. We now have fifteen Perqs at CMU, and work on Spice is
proceeding rapidly. We continue to be on the lookout for new hardware that can
be used in the Spice system in years to come.
Our criteria for machines may not be the same as other people's; we are heavily
committed to "high-end" personal computers, and the software available was
relatively unimportant to us. However, if Mesa and its compilers were freely
available the Xerox machines would have been very attractive.

Many of you in Xerox are aware of a newly created Arpanet distribution list
named Apollo. It was established to promote discussion of personal workstation
computers. As you might expect, much of the recent discussion has involved the
Xerox 8010 Star information system. Because many of the messages ask for
information about this product and its associated development software, you may
feel tempted to reply to some of them.
It is ARPA policy that the Arpanet be used only for government supported
research and development. It is against Xerox policy to use the Arpanet to discuss
products. It is completely inappropriate to use the Arpanet in a way that may be
construed as selling or promoting a Xerox product (or future product). Xerox
employees use the Arpanet for ARPA related research purposes only, not for
answering questions or distributing information about our products.
Questions from potential customers about the Xerox 8010 and other OPD products
should be referred to Arnold Palmer, Field Sales Manager, Xerox Corporation,

Last week we had a briefing on the Star, so I will relate what was said.
The processor is a D3 machine, and is claimed to run Mesa about
3 times faster than a D0 or a Dolphin. The D3 is a 32-bit, virtual
memory design. The Star only has about 200kb
of memory on it, expandable to about .5 megs, but there is every
reason to believe it can have a lot more than that on it. The
office automation software is all written in Mesa and the base of
the machine is Pilot, but you can't get to any of this. The is a lot
of discussion about making the Mesa environment available, but so
far there is a negative corporate attitude. If they would just
realize how neat that would be.... Anyway, the office software is
pretty classy, but their pricing is repressive. By the time you
license all the software (math editor, graphics, spelling corrector, etc),
which must be done for EACH machine, you add about $5K to the price.
The killer, however, is software maintenance for that machine will
be close to $500 per month!!!!! The pricing structure allows hardware
quantity levels to count the various servers (com, file, print, etc)
as well as Stars because they all use the same CPU box, but
quantity levels for software count only Stars. Software for the
other servers is priced the same way. The basic file server does NOT
come with the electronic mail facility. That handy option costs extra.
Rumors abound pertaining to the transport of Smalltalk and Interlisp
to the machine, but like with Mesa, Xerox doesn't see any demand for
user programmable machines. Moreover, if they can continually
squeeze money out of you for software, it is to their advantage
that no one else can build software for it. (Personal comment)
If any mere mortal (other than MIT, CMU, and Stanford) can
shake Mesa out of Xerox, let me know.

Kirsch has an extremely valid point. The fundamental question is what
leverage does computerization provide in doing a function. However, let's
not be miserly--even Xerox STAR's are incredibly cheap as an investment,
so the amount of leverage they must provide is small.

We had an Apollo presentation, given by Dave Nelson, one of

one to be to others of their (Domain) rings.
It was my impression that the basic network environment is
strictly message/packet oriented, without connections or other
efficiency mechanisms. Nelson pointedly stated (it was too
affirmative to class as an "admission") that they were not
oriented toward file transfers . Such things can and are done,
but the environment is not tuned to them.

I would like to correct some erroneous information about Smalltalk and the Star.
o Smalltalk "will NOT be released on the
STAR or anywhere else" -- a "small
outfit in Silicon Valley" (not PARC --
I'm not sure who they're talking about)
licensed it to HP, TI, and Apple. When
the STAR marketing people found out,
they "put a stop to it"
The truth is that LRG, a group within PARC, has licensed Smalltalk-80 (the only
Xerox-authorized version of Smalltalk to be released) to a number of micro- and
mini-computer manufacturers. The release consists of detailed specifications for
the machine-dependent kernel, plus a mag tape containing the rest of the system
(windows, editor, compiler, file system, etc., etc.) Several of these manufacturers
have made excellent progress on implementing the system, to the point of having
windows appear on their displays. I can't comment on the specific list of
manufacturers, since we prefer to let them make their own announcements. The
Star marketing people have not exerted any pressure in either direction with
respect to this; the release/license process was properly cleared with our legal
department and all relevant product organizations within Xerox, and we are
currently working out ways to license the system to manufacturers (and
universities) beyond the original group. I can't comment on the availability of
Smalltalk for the Star, except to say that the Star hardware is definitely powerful
enough to support Smalltalk.

Who were "the STAR people" that came to talk to you?
Smalltalk IS being released by PARC this summer. There was a big presentation
on the subject at this year's NCC. Apple, DEC, HP and other companies are
doing research into implementing it on their machines. (In fact, one of the
primary Smalltalk implementors, Larry Tesler, is now at Apple and was one of
the speakers at NCC.) A huge article on the subject will appear in the
August issue of BYTE.
The deal is that PARC gives you an "image" file on a tape, whichcontains
all of Smalltalk ready to run. To run it, you have to implement an
interpreter on your machine for the 256 Smalltalk bytecodes. Just like you
can run Pascal, if you have a P-code interpreter.
(I don't think anyone at Xerox will beat up on me for this message; all of
it comes from strictly public sources.)

Forgetting for a moment about Xerox marketting, Xerox intends to
release a book on Smalltalk called Smalltalk 80. This version of
Smalltalk is intended to be easily portable. There was some
discussion within Xerox legal about whether the Smalltalk virtual
image would be released. But the book which describes the interpreter
plus the virtual image would result in a very easily portable
language.
One could then port it to the machine of your choice, including the
STAR, assuming that you could PROGRAM the STAR. When MESA gets
released you will be able to implement it in that: but a better place
is microcode. I haven't heard anything definitive about whether Xerox
intends to microcode the Dandelion (STAR workstation) for Smalltalk.
Xerox marketing wasn't trying to mislead, I'm sure. They have no
interest in marketing Smalltalk; just word processing.

16-Bit processor (MC68000)
19" color monitor
1024x768 viewable bitmap (in a 1024x1024 bitmap memory)
Up to 256 simultaneously displayed colors
Palette of over 16 million colors (i.e. 8-bit DAC for RGB)
10MB Fixed Winchester Disk (8.4 MB formatted)
Dual floppies
light pen, joystick
Maximum of 16-bitmap planes (no more than 8 displayed at once)
Maximum of 2MB of processor memory
Rand reviewed this machine last year and might have purchased one if it
hadn't been quite so new (at the time they had not delivered any, and we
needed a mature system). When I priced it, a useful system was running
around $60K.
Oh yes, they're planning on running the 68000 unix look-alike.

According to a sales engineer I spoke to in Atlanta las week, the software is
IDRIS, Whitesmith's UNIX look alike, none of which had yet been
dleivered to them (or any one else???), nor could he say when an
order placed for the IDRIS software for Chromatics be filled.
If color isn't mandatory and if you are willing to think about systems
with not yet ready software, ask Three Rivers whether/when the Tom Duff
port of Coherent, the Mark WIlliams company version 7 unix look-alike,
will be sold for PERQ's

p.s. A great deal of the Apollo software is also "not quite ready" but
they at least don't advertise it. It's just that Apollo's will presently
do much less than the world of WorkS expects them to. I will flame
after some less biased view of this week's Brown University
Apollo Users workshop appears in this forum.

The Apollo network is a token network as stated. However the
Cambridge folk are not the originators of the token ring idea. In
fact the Cambridge ring is NOT a token ring. It is a slotted ring
with small slot size.
Tokens rings come via Newhall/Farmer - the DCS process addressed
ring (the first with a real token) - the LNI/MIT LCS I ring with
the Prime ring being derived from the DCS instance.

In response to the message sent 23 Jun 1981 (Tuesday) 2308-EDT from DREIFU@WHARTON-10
One fine point on local networks:
a) The ring produced by Prime Computer is a "token passing" design,
and it appears that the Apollo system follows this design.
Token passing systems trace their roots back to the work of
Newhall and Farmer at Bell Labs.
b) A recent message suggested that the Cambridge Ring
was also in this family; however, that design would more properly
be described as an "empty slot" ring. The empty slot systems trace
their roots back to the work of Pierce, et al., also at Bell Labs.

I have seen a two node configuration of Apollo's working (Mountain View
Branch), and was able to see a file shipped from one node to the other,
and to compare the times required to count the number of lines
in the local copy and also in the remote copy, accessed via "//<host>file..".
It was interesting that in the first test, the times local and remote
were essentially; after a reboot, the remote time increased slightly
(about 5%). This was explained as an effect of the Unique global ID; in
the first test, the system "knew" the local and remote file by the same
Global ID, and also that the local copy was in the Memory space.
I do not recall the exact number of lines (it was a LARGE file), and the
time was about 1minute. The timing was done by submitting to the
SHell the concatenated commands:
time; countlines //host/... ; time; (This is NOT verbatim).
We also saw the multiple INPUT/OUTPUT windows and PADs working, the
various Display Manager options, the ability to Grow and Shrink windows,
the ability to run separate processes in each Window (in this case,
it was Edit in one, LIST in the other, as I recall).
We were not able to see any real graphics (ie line drawing), tho a small
program was demonstrated that was able to BLT screen areas around.

Bruce Daniels wrote asking about the configuration of my CT system at

Workstation with 256Kb RAM, 5Mhz 8086, 2xRS-232, Centronics
printer port
10Mb 8" winchester (Shugart 1004 drive)
0.5Mb 8" floppy (single side, double density Shugart 800
drive)
Soon to be added (awaiting delivery only):
Additional Workstation to be clustered on the first using CT's
local network (multi-drop, 615Kbaud, half-duplex, RS-422 line)
GE 510 300lpm printer
For software I have:
CTOS multi-task, real-time OS
Pascal
FORTRAN
Word Processor
ISAM
Forms
Sort/Merge
Multiple-window Screen-oriented text editor
Basic
and several programs of my and others design...
For those of you used to home computer prices you may find things just
a bit steep, but if you compare performance per dollar it seems to be
a fairly good deal. Price for a 128K dual floppy system is $13,300 in
unit quantities. The 256K winchester system comes in at about $21,000.
All stand-alone systems include OS (linker, assembler, screen-oriented
editor, and asynchronous terminal emulator). Additional workstations
go for $6,490 for a 128K version or $7,900 for a 256K version.
I like the system a lot. It is easier to use/develop software for
than my PDP-11/23 with RSTS/E was (I know most of you are UNIX hackers
but you have to take what you can get).

I agree wholeheartedly with the comments put forth in JWALKER's
message on Personal Workstations -- who for?
There currently seems to be one of two approaches taken in
applications for office automation:
(1) Develop an application that answers a specific
functional requirement. For example, a budget
preparation tool or a project management (pert)
tool. JWALKER is very right in stating that all
to often these applications are written FOR the
functional and indeed do narrowly define the scope
and processes of usually complex functions. What
results is an application that does not quite do the
job and is too inflexible to mold to the nuances
of the functional task which it attempts to address.
Bottom line is that the functional user must adapt
the way she/he does business to the application.
(2) Develop a general tool (or set of tools) that can
be used in a wide range of functional applications.
Here I am speaking of a message system, and editor,
a suspense tool, etc. While these give the functional
user much more flexibility on how she/he will use
the tool in his/he job, often this adaptation is
cumbersome. Many time we have given a message system
to a user with the response being "What can I use this
for in my job?" Then we explain how and they ask why
and we explain more and they ask how and why and....
Thus we seem once again to be telling them how to do
their business.
The folks here in are branch spent an entire day discussing this
very problem last week. What we came up with was that there is
a need for general tools AND a need for specific applications.
The problem really is that we are addressing office automation
as a tool or an application and it is really much richer than
a single tool (or set) or a single application.
What we are planning to do is to develop an office automation
system which puts emphasis on the work ENVIRONMENT. We are
going to try to structure the user's terminal like a desk.
For example, when they reach for their inbox they will end
up in the mail system. If they suddenly get a call in the middle
of reading their inbox they will not have to exit the
mail system to get to their telephone pad or calendar or whatever.
They will simply reach for it. The system will suspend processing
in the inbox and move to the telephone pad or whatever the user
wants. At the conclusion of the telephone call the user will
say something like "continue" (or hit a button) and the system
will remember where he/she was in the inbox.
In this type of environment tools and applications are transparent
to the user. They are called into use by the system, not the user.
I would really appreciate any comments or suggestions on what this user
environment should look like or include.

From: Steven H. Gutfreund <SHG at MIT-AI>
To: WORKS at MIT-AI
cc: Rivanciw.DHQ at UDEL
I would like to comment on one part of Randy Ivanciw's letter about
the need for an integrated environment for workstations. (Which I
believe much of the world is coming around to endorsing even if they
do not know how to do).
Randy gives the example where one is reading a mail inbox and gets a call
on the phone. It would be very useful to be able to drop the mail, pick
up the phone, answer the call, and then return to one's mail.
With iconographic systems (such as STAR or SMALLTALK-80) this would be
quite simple. One would use the mouse to drag the cursor away from
the current icon (be it editor window, mail inbox, virtual terminal)
and position the cursor to the telephone icon. There one would
expand the telephone icon and answer the phone. Later one could return
to the old mail inbox icon.
However, there is a problem here that several Human Factor's people
have pointed out. That is, one could easily have quite a few "pushed"
windows, each one deep in some command dialog. The Human Factor's
people have pointed out that humans have a real scarcity of short
term memory (about 4-7 chunks). Clearly, we humans are going
to have a real problem understanding what was going on in our
workstations after a couple of interruptions.
Therefore, I would like to propogate, to designers of workstations,
a user interface folk theorem that I heard recently: NEVER HAVE
MULTIPLE LEVELS OF STATE ENCODED INTO A DISPLAY.
Naturally, I am curious as to what others feel this restriction will
do to programming a user interface. I would also be interested in
collecting other folk theorems.

The second part of Rivanciw's recent comments on Personal Workstations
sound very much like the DATALAND concept of Nicholas Negroponte of the
Architecture Department at MIT& Negroponte's ideas have progressed to a
somewhat more grandiose scale. He has built a special room containing a
wall-size screen and an armchair with input controls on both the arms.
His basic concept is that people often organize themselves S@ATIALLY
rather than with the alphabetic keys by which opdinary random data files

One thing we should avoid in designing tools for use by non-programmers is
condescension. Elegance of design, yes, buT simple-mindedness, no. There are
three aspects I see to this:
1. It should be possible in a short period of time (perhaps less than a day,
depending on the application) to learn enough about it to be productive.
2. The expert user should be able to make maximal use of the features available
without being hampered by the requirements for (1).
3. A smooth transition from (1) to (2) should be possible.
An excellent example of this is the Tops-20 command language (EXEC). I
assume most of you are familiar with it. By combining command completion
(recognition), abbreviation and menu-on-demand, the needs of expert and
novice are served equally well.
Another example is the Emacs text editor. It is used by nearly everyone
here, including administrators and secretaries. It is possible to learn
enough in an hour to make productive use of it, then acquire facility in
a`vanced FeatuRes (editing modes, TAGS, word abbreviations, etc.) to make
it a powerful Tool. In addition, since it is programmable (all key
Definitions are soft), a Wizard can a`d FeatuRes fop spEcialIzed
applications. (Admitp KI1rP⊃βvyβ?;*β'9β&C↔'I¬∪'∨#"β7'≠ ∧π>␈]LBπ/<T¬$ 9tε∂~ ⊃PWπ-|w⊗∞]]⊗v:

Peter Deutsch requested that I send along a short summation of
DARCOM's system architecture for OA (in particular hardware, software)
so here goes.
The software that DARCOM is running in its OA architecture is UNIX.
Right now we have some v6, some pwb, and some v7. We will standarize
on the latest release of UNIX from BELL. Our tools are currently all
in the public domain except for an office package that we have running
on our HQ machine called OPUS. The public domain software includes
NED, ED, MSG, MS, and (I think its public) XMSG, as well as some
home grown tools such as a suspense program (which is really a shell
routine) and an automated weekly activity report.
The hardware for our architecture is simply any machine that runs
UNIX. Currently we have 11/70s and ONYXs operational. We are
looking into the C machine from BBN. Of course we are interested in
the latest announcement on ZENIX (Unix look alike for any 16-bit
micro).

Yes, the Dolphin is being sold by XEROX EOS as the 1100 "Interlisp Machine."
It is about $60K, last I heard (someone at Rand or ISI correct me here.)
It is also about 3 times as slow as the Dandelion (what's inside the Star),
according to very reliable people at PARC; that is surprising, since the
Star costs little by comparison ($6K in parts costs, I've heard.)
Also, XEROX is now putting up Smalltalk on the Star, for internal use.
I have no idea, and I suppose neither does XEROX, if they'll ever release
it.

Looks like a true rumor to me. The following is excerpted from a PARC Forum
announcement sent to all users of the Xerox message system. It was an open
forum, so this is public information.
-----
The Xerox 1100 Scientific Information Processor, currently being marketed by
Xerox EOS to the research community, is a Dolphin processor running
Interlisp-D. Not only does this configuration provide comfortable
interactive performance, but the availability of Interlisp on such a low cost
machine makes economically viable the widespread use of knowledge based
technology, such as the deployment of intelligent servers in a distributed
network environment.

(Xerox EOS = Xerox Electro-Optical Systems of Pasadena, Calif.)
The "Dolphin" is the same processor used in the Xerox 5700 laser printer.
This is NOT the "Dandelion" processor used in the Xerox Star.

The Xerox SIP 1100 (Scientific Information Processor 1100) is really
going to be marketed by Xerox EOS (Electro Optical Systems). Here's
the deal:
It will sell for $60,000 a copy
It will have Interlisp. It will not have Mesa. It will not
have Smalltalk. (Maybe later it will, but they are not
promising it today).
It will have the 3mbit Ethernet. 10mbit later, but not this
year.
They wont sell any unless they get 'some minimum number of
orders'. The number that is most often mentioned is 40. (That
is, 40 altogether, nationwide. Not from one customer.)
The kind of maintenance available depends on where you live.
If you are not in LA or Palo Alto, then you will probably have
to do maintenance by paying time, materials and travel. The
other possibility is to stock spare parts and swap boards.
XEOS is considering, and would prefer, to have a complete
maintenance organization if there is the interest and enough
Dolphins in one place.
This deal is taking place because, among other reasons, ARPA
is looking for a way to get personal, networked Interlisp
machines to some of their researchers.
Xerox is accepting purchase orders now.
Let me know if you want a phone number for a Xerox contact. Your
local sales organization will probably not be of any help.

The commercial success of the personal workstation is largely a
matter of economics. Irrespective of the technical merits of the
various machines, they complicate installation planning by introducing
a new type of capital expenditure which typically cannot be financed
the same way as large, centralized computing centers of the past.
This may be an advantage or a disadvantage, depending on your point of
view.
On the negative side, the incremental cost of placing one new
user on a personal workstation is very large--the cost of the
workstation plus a local network interface and cabling, at least. For
centralized systems, the cost of adding one user to the community is
the price of a terminal and a terminal port (which is often dial-up,
and amortized over many users). Certainly there are many hidden costs
involved in either case, for example, the degradation of performance
of the centralized system as the user community expands; nonetheless
the capital expense of the physical equipment represents a fundamental
barrier, an "activation potential" if you will, for new users.
Are we making good use of the technology? From one point of
view, the development of personal workstations has been directed
towards increasing the computing power available to individual users
(the "KA-10 in your office" philosophy), at roughly constant or even
increasing capital cost per user. Can comparison shopping in the
small systems marketplace, a highly competitive part of the economy,
be a better idea in some cases?
In particular, I remember one reader of this list commenting to
the effect that he wasn't interested in small systems (e.g., micros
with 16-bit address spaces). I use an H89 (Z80 based system, 48K
bytes of RAM, 5" floppies) at home, and for the sake of comparison I
ran the Baskett test on this machine. I transliterated the program
into C for the C/80 compiler as directly as possible (almost token for
token), and even on the "small" system the object code is only of
modest size. The execution time was 542 seconds, as opposed to about
40 seconds for the Perq. This Z80 machine runs at a 2 MHz. clock,
which can easily be doubled to 4 MHz. reducing the run time to 270
seconds, about 6 times slower than the Perq.
I do not mean to suggest that we should all be using CP/M and
8-bit micros. But neither does it seem wise to pass over these "small
workstations" as being insufficiently powerful; they can be extremely
cost effective. The question is not whether these systems should be
used at all, but how they might be integrated into larger
environments. Suppose a user can afford to pay $3000 (about twice the
cost of a terminal) for a VT-103 (a VT-100 terminal plus LSI-11
processor). What functions can we place in this device to improve
performance? How should it be integrated into the network of personal
machines and shared hosts? Could we, for instance, support a window
package for the VT-100? (In fact, we can; examples already exist.)
From my experiences at BBN, it is clear that the economics of
personal workstations can be very complicated. Two troubling effects
that may be general phenomena are the sharing of one "personal"
machine by several people (and corresponding problems of data
security, authentication, etc., which have been pretty much ignored in
the "personal" workstation model), and the inability of low budget
projects to get into the game at all (it is difficult for people on
different projects to share the same machine, for many reasons).
I would be interested to learn how others are resolving these
issues, whether in software or by direct administrative control.

I agree that it is hard for a user to keep track of a stack of
interruptions. Having to maintain a mental model of such a stack, and
having to remember what "exit This command level" will do, is a real
paif. Most interactive systems I have used have suffered from this
problem. The Lisp Machine solves the problem by having all of the
user's activities be at the same "level". There isn't any command
processor that "calls" programs which then "return" to the command
processor; you just move "sideways" from one thing to another. No
stacks are involved. (Actually there are stilh a few stacks in the
system, but they are being removed.) (There are some cOmmands that mean
"switch back to the previous thing I was doing", which you sometimes
want, but nothing forces you to use these commands. (If you gives such a
"previous thing" command over and over, it switches between the same two
things, in case you were wondering.))
Not only is this easier to use, but it is more powerful. If you are
reading your mail and you are interrupted by a phone call, you can go
handle the phone call, and then put the caller on "hold" and go back to
reading your mail, and then get back to the phone call. That is, you
need not maintain a last-in first-our ordering among your actitivies.
This is one of the things I think is most valuable about the Lisp
Machine's overall user interface structure.

You asked, "The iNstantaneous bandwidth of such a transmissign system ic
rery high. So who needs a Chaosnet?" This was presumably in reference
to the use of fLoppy disks for inter-workstation file transfer.
While the instantaneous bandwidth may be the same, the overall bandwidth,
counting the playing with the physical disks, is much lower.
Furthermore, the net is superior because (1) you can't do remote lkgin
ovep flOppy disks, nor asking what time it is, nor askifgwho is logged
in, nor anything elSe besides file transfer, and (2) it is very clumsy,
especially if the other machine is across the street or down the block.
Direct and easy access to a shared file server is important.

The recent discussions of address space size, remote file access, etc.,
brought back to my mind the IBM System 38 - specifically the notion of
only one kind of addressing (48 bits in that machine) which is used
to access "main memory" or data on secondary storage - rather than
having files, there is the notion of various "access paths" possibly
existing through a great heap/swamp/"data base" of bits and bytes.
As far as I know the machines under discussion generally belong to the
Multics/Tenex/Unix school of thought that on the one hand, there is
memory, and on the other hand, there are files. All sorts of nasty things
like networks, terminals, users, etc., are mapped into one of the two
(usually files). But it seems to me more desirable (in principle at least)
to have only one kind of thing ala S/38, with various notions of access
paths, objects, classes of objects, etc.
I for one would be interested in knowing if my feeling is shared by
others, and also whether there are any plans on the part of the research
groups or other entrepreneurs to build such machine/software combinations
for those of us who would rather not program in RPG.

In Steven Gutfreund's recent message on user environments he mentioned
that it would be best to "NEVER HAVE MULTIPLE LEVELS OF STATE
ENCODED INTO A DISPLAY". I am not quite sure what Steve is really
going for here - does this mean never to have more than one level
on a screen at any given time? or does this mean not to have the
system track where and what a use was doing? I am not sure.
My thought are that in my work environment I am constantly being
interupted by phone calls, urgent messages (electronics as well
as paper), and drop in visits. Often times I can not remember
where I was or what I was doing (Steve mentions this problem in
his message). It was my hopes that an office system could help
me keep track of where I was and what I was doing.
For example, right now I am composing a message to the WORKS
mailbox. Suddenly an urgent electronic message header comes up
on my screen that I must answer right now. I abort this message
(naturally saving the draft) and read the new message, check other
files (calendar, saved messages, suspenses, etc) and compose a
reply. That might take 15 minutes. In the meantime my phone
rings or I have to make a call that requires me to divert my
attention elsewhere. Then someone stops by my desk to tell me
about their weekend or talk about some configuration.
Bottom line is that I forget all about this message. I simply
did not remember where I was or what I was doing. Several days
from now I'll see a file named DRAFT-WORKS and wonder what it
is. I'll read the file into the editor and suddenly remember
what I was doing, but by then the reply may not be worthwhile.
In a very rich user system, the system would keep trach of where
I am so that when I said continue it would take me back to this
message reply and I can finish it. I feel that this tracking
would have to go at least 3 or 4 levels deep.
What are some other thoughts?

Mike's response (more like a Bronx cheer) forces me to clarify some of the
points I was trying to make:
First, I could not say that the design of Unix is not simple, clean and
well-integrated from top to bottom. In fact, I only objected to one thing,
certainly not a central point, which is the cryptic command names (cat, mv,
rm, sh, ls, grep). These are almost as mnemonic as PDP-10 opcode names.
(Jrst enough for some, I suppose.)
Second, Emacs is no Mies van der Rohe creation. The implementation is at
three levels, MIDAS, TECO, and Emacs keyboard input, the first two of which
are incompatible with each other and sane human beings. The single
character commands are also cryptic, but there is readily accesible online
documentation for them. Common editing commands are often used in rapid
succesion, necessitating brevity. (Although I believe I saw an editor
described in Software P & E using the Tops-20 COMND JSYS which looked
somewhat interesting for novices.) Mike (apparently) objects to the use of
extra shift keys for commands. This is required because there is no
"insert mode" in Emacs; what you see is what you get. That is what
distinguises it from every other editor I have used, and is the most
important aspect of its design. Also, by not requiring special editing
keys or other input devices such as a mouse, a good typist can remain in
registration when entering commands.
Unix was designed when CPU power, memory, address space and terminal
bandwidth were scarce resources. Its popularity (in academic circles) is
due to its accessibility, portability and malleability. I only hope
in extolling its virtues we do not overlook its shortcomings.

P.S. Sorry for getting a little off the topic of personal workstations per
se, but I believe this is relevant to system design.

I have some literature on the ALANTHUS System 1000 workstation. It is
a 16-bit machine with high resolution display (15"), up to 1M of RAM,
and a set of either twin 8" floppies or a winchester drive. It is
configured in an interesting manner, with the "guts" (RAM, controller,
etc.) in a chassis sitting upright on the desk with a clipboard on
the3 side to disguise the box. This allows the entire system to be
off the floor (excepting mass store, which can be across the room).
They claim the desktop units can be lined together via a high speed
LAN, providing multi-station access to shared resources. They are
on the Federal Supply Schedule, which (I assume) lends some
respectability to the enterprise. They use both the Intel 8086
and 8088 in their various configurations.
Sounds like they are using Convergent Tech gear. Does anybody know
otherwise?

Your information is correct. The Xerox 1100 is a Dolphin with
Interlisp. Its speed is approximately 1/2 KA-10 equivalent,
assuming you buy enough memory (~ 1 MByte) so that paging doesn't
kill you. It comes with a 600 x 800 bitmap display, a 28 Mb
non-removable disk, and a mouse; I'm sure some flavor of Ethernet
will also be available. I have no information on purchase price,
delivery schedule, etc. as yet.

Randy Ivanciw is gorrect when he says that a system could be
built which would "refresh" the user's memory when he returns
to a window. However the problem with arbitrary state diagrams
in dialogs is that such a smart assitant would have to understand
all transitions that a user could have made. Pre-designing
such help into a dialog is a massive chore, and therefore rarely
done well or done at all.
It seems to me that if one is to follow the old maxim: WHAT YOU
SEE IS WHAT YOU GET. Then we should not have state diagrams in
dialogs which cause the user to be able to read the entrails of
his/her display to figure out what has gone on before he/she
left a window.

Whoever mentioned the MIT Lisp machine solution hit the nail on the head: if
(1) there is no notion of "nesting" of suspensions, but rather simply a pool of
tasks in various stages of completion which the user can switch between at will,
and (2) every partially completed task is represented by a VISIBLE OBJECT on
the screen, then there is no issue about forgetting partially completed tasks,
being forced to complete them in the order they were started, etc., etc. I believe
(at least I hope) the Star works this way, since all the experimental
multi-window systems at PARC do.

I couldn't agree more with Bill Barns. Simplifying storage organization
is an important aspect of the more general goal of simplkfying the
user's perception of what is of necessity a very complex environment.
There is some support at Stanford for this goal; in particular we would
like to be able to offer users of SUN (Stanford University Network) a
simple coherent model of both SUN and (a rough approximation of) the
world outside SUN. Some vague thoughts along those lines appear in
<CSD.PRATT>SUNUI on Score. Brian Reid and I are mulling over such
ideas during this summer.

Poor Multics. People seem to attribute all the limitations of
its imitators to the original. One of the major advances in
Multics was its large address space and the uniform treatment
of the address space. Files are not an intrinsic part of
Multics -- only a convention for access memory through I/O
routines. There isn't even I/O -- just a set of conventions
for writing for writing an I/O interface module.
Yes, the system/38 does work out a lot of the ideas and I still
feel it is IBM's most advanced system and have suggested people
look at it as a model. But from what I hear it has not solved
its performance problems, though the model of using gobs of
computational power to provide a powerful interface is the
correct one.
The other difference is that Multics provides the full power of
its process to its users. The System/38 is packaged like a
real computer but seems to be much closer to an assembly
language/PLS interpretter running the user code. It was clever
to invent the term vertical microcode, it means that they don't
need to give you a listimg of the operating system and are free
to change the internals as long as they preserve the user
interface.
Overall I think that the System/38 is a winner and one day IBM
will tell people that it is more than a System/34 upgrade. On
the other hand, I have not used it directly and RPG III (a VHLL
production language if you want to look at it that way) is the
only language currently available. It is also a little on the
expensive side, even compared to a Star.

Original statement:
As far as I know the machines under discussion generally belong
to the Multics/Tenex/Unix school of thought that on the one hand,
there is memory, and on the other hand, there are files.
-- Barns at OFFICE
Comments:
Multics does not view files as something fundamentally different
from memory. Rather, it was the first system to support a uniform
single-level memory system consisting of variable size objects
(segments) from 4096 bytes to 1 megabyte in length. Files were
simulated in Multics for compatibility reasons only, and files
were constructed out of segments.
-- Paul A. Karger <PAK at MIT-MC>
An important correction for all of you who have never used Multics,
and are constantly assuming that it is like UNIX or TENEX. It is
not. Barns, for example, says that Multics/TENEX/Unix differentiate
between files and memory (and that the S/38 doesn't). Multics was
the first system to do away with the concept of file--Multics "files"
are merely part of its large virtual memory, and are accessed via
pointers. S/38 has few new ideas in this area, and a lot of crocks.
Pish tush. -- DPR at MIT-XX
You are completely wrong in classifying Multics in this group.
In Multics, there is absolutely no distinction between "memory"
and "files"; there are just segments, which live in a hierar-
chical file system and are addressed directly. The System 38
is a spiritual decendant of Multics in this regard.
Just because an idea is old-fashioned does not mean you should
identify it with Multics. For all Multics's problems and extreme
age, it is STILL ahead of its time in some ways. Sorry for the
irrelevance of this message, but I couldn't just let this go by...

Now that half the Multics users in the world have voiced their
displeasure, let me try to say what I was really trying to say
before, hopefully in a less offensive manner:
During the time period when Multics was born, that system
and others made varying uses of the idea of a single level
store. Naturally different people came up with different
hardware/software approaches and solved different subsets
of the universe of possible situations. Since then we have
had Tenex and Unix which have made their own contributions,
and also some steps backward because of the desire to make
something that doesn't chew up a disproportionate share of
a timesharing system's time. (Yes, many others too, but
Tenex and Unix are perhaps best known.) More recently the
S/38 has attempted to go back to some of the more general
ideas, which is noteworthy in that it is not such an enormous
processor, nor is it intended to be a timesharing system of
the flavor of Multics or Tenex or Unix. Unfortunately there
are also many unfortunate things about the 38 as now packaged
- notably the lack of programming languages that many of us
like to use, or reasonable substitutes.
Now it is my impression (unsupported by hard data) that the
38's processor is more or less in the same ballpark as (some
of) the workstation processors. This suggests that it is
not unreasonable foR someone who has a mind to, to make a
programming environment on these machines, or ones like them,
which will give us a simple means of accessing data For the
purpose of local computation by the 'owner' of the workstation
and only apply restrictions on access tk people elsewhere in
a network. I sugcest that in the nicest dorm, this meanq that

Bill, the system you describe (System 38) is just a
capability-based machine, which is certainly old hat by now.
Unfortunately, this idea still seems to be barely catching on in
the "real worhd." MoSt of the seminal systems (CAL at Berkeley,
Hydra at CMU, and the Plessey System 250) were done and finiShed
yaars ago, and yet there are only a few commercial systems which
reflect this elegance of architecture (S38, Intel's 432 (iN some
sense), some ICL machines). Others are working on systems which
embody these ideas (H-P's Bridge project, the S-1 project), but
most of them bastardize the design for "practicality". I surmise
that capability-based systems are finding life difficult because
no one ultimately understands how to deal with them practically
(e.g., the Hydra folks discovered quite a few problems with
accounting (who owns an object?), backup, recovery, etc., though
they also made great strides with some of the harder issues
(mostly reliability).) I think a large percentage of us would
be delighted to have a true capAbility-based machine if the
Performance were up to what we've cOma to expect from current
architectures, buT that doesn't seem to be around the corner (at
least in any useable way: S38 hides all its good design from the
User and masks it in the usual nonsense IBM business software.)

In response to your message of Thu Jul 2 "0:26:38 1981:
Bit Map refers to the way a picture is stored, i.e. one
bit (or aggregate of bits for color) of memory for each
addressable point on the screen. As opposed to the older
"display list" technique where the picture is stored as a
list of line segments, etc.
Raster-scan refers to the method by which the picture is
refreshed on the screen, in this case, as a series of
horizontal lines, starting at the top of the screen and
moving down. As opposed to "stroke writers" which move
the beam in arbitrary directions to draw individual
graphic primitives.
The earliest displays were stroke writers. The TX-0 at MIT
moved a beam on a CRT under the direct control of the CPU.
In some sense, this was the first pepsonal computer, as
refreshing the display didn't leave too many cycles for
anything else. Later, the direct view storage tube (DVST)
allowed the picture to be written just once instead of
being refreshed 30 or more times per second. Only problem
was that the only way to change anything on the screen was
to erase the entire screen in a blinding flash which took
.5 secOnds. By the way, contrary to current publicity about
the STAR, the Advanced Remote Display STation (ARDS) storage
tube terminal was the first to offer the "mouse" as an input
device.
Stroke writers are still in common use in the CAD/CAM area.
They typically employ high-performance (expensive) analogue
circuitry to draw vectors of much higher resolution than are
currently feasible with raster displays. Resolutions of
4096x4096 are not uncommon.
The raster scanned bit map display is rapidly taking over
the display scene. It is cheaper to build circuits which
move the beam in nice sraight lines across the screen than
to build in the ability to turn corners.
To answer your question, for all intents and purposes,
raster-bitmap and bitmap mean the same thing.

1. A capability is just a fancy name for a pointer in a
machine that doesn't have enough address space to begin
with.
2. The current hangup of capability machines is their
unwillingness to do garbage collection. (Tracing, etc.,
that is.)
3. Lisp was the first capability machine. It is true that
the objects are quite small in the original Lisps, but
with newer Lisps having vectors, strings, objects,
classes, flavors, and what have you, they have all the
power of Hydras, 432's, etc.

I must be missing something. Barns wishes for "an n-bit
number which is absolute for the whole workstation". Isn't
a reasonable-size conventional virtual address a solution to
this problem, provided that the operating/language system
doesn't allow you to fabricate addresses? That's the only
sense in which the Lisp Machine solves the problem, and it
only does it by virtue of NOT having any local capability
for named files. The LM doesn't provide any facilities
that replace a local file system, either, e.g. there are
no tools in the system for constructing and manipulating
directories of variables. Furthermore, the LM would be
helpless without the presence somewhere in the network
of some very conventional file systems which handle messy
questions like space accounting, periodic backup, user
authentication, etc.
Of course, if you want local objects to be remotely accessible,
then you do need something much more like capabilities. Given
that mainframes (processor + memory) are so cheap these days,
compared to the cost of a reasonable-size disk, I'm more
inclined to favor putting all potentially sharable objects on
a separate server mainframe and let workstations either cache
them on their local disks or get them over the network whenever
they need to. This requires some architectural changes in the
world to make that network access comparable in speed to, say,
something between a cache miss and a bubble memory access, as
opposed to a disk access.
To the best of my knowledge, Star, like the research machines
(Dolphin and Dorado), has a conventional paged address space;
the Star OS provides for mapping full or partial files into
this space, like Tenex or Multics. The OS happens to be
optimized for mapping sequential runs of pages of a single
file into contiguous virtual pages, but that is an
optimization only.

It is little known, but the new versions of the Honeywell 6000
have a memory management unit, internally known as NSA (for
New System Architecture, I think), which makes the machine a
form of capabilities machine. It is elaborate and baroque,
but underneath are some very powerful ideas. The architecture
supports multiple independent domains (where a domain is a set
of addressing capabilities), such that a process can consist
of many domains.
Honeywell is slowly attempting to extend the old GCOS-III
operating system to take advantage of this, and the new
version is being called GCOS-8. In addition, Honeywell
some years acquired the XDS Sigma (formerly SDS) business,
together with a little-know, but much loved by its users,
system called CP-5. The group that moved over from Xerox
as part of this deal convinced Honeywell that the operating
system could be ported to the Honeywell processor, and have
produced an interesting system called CP-6, which takes
advantage of the domain features in some nice ways. For
example, a process can have a debugger in one domain to
debug code in other domains, putting it far ahead of
almost any other system I know (including UNIX) in this
area.
Those interested in system design and memory management
approaches ought to be aware of what is going on here. It
represents a significant extension to the thinking about
domains and capabilities. Unfortunately, there is little
in the way of reports or other decent documentation, but
perhaps some beating on Honeywell would produce something.
I'm not sure that this is the right forum for this discussion.
It would be nice if someone would start and manage a conference
dealing with operating system and system design issues. WorkS
and InfoMicro seem to have lots of people interested in these
topics, but they are really focused a bit more narrowly and
differently.

Subject: EMACS -vs- UNIX

Folks -
"Eric Benson's message implicitly compares the Emacs
design with UNIX. In his words, Emacs is elegant, UNIX
arcane."
Both this comparison and the conclusion disturb me.
Comparing an editor (which can be thought of as having 3
levels) with an operating system (which has many levels of
complexity) is kind of off-the-wall, but lets play along...
INTENT: The intent of EMACS (as I see it) was to
provide a "what-you-see-is-what-you-get" screen editor
which behaved similarly over a wide range of terminal
keyboards (and terminals), and to permit construction
of Macros to implement higher-level features (LISP
indenting, etc). The intent of UNIX was to provide
a powerful, plesant, and consistent environment for
Computer Science types to experiment and build tools
in.
In a word, the intent of UNIX is "Software Tools",
whereas the intent of EMACS is "Software TOOL". Humm.
USER INTERFACE: Everybody will be quick to agree that
EMACS has a simple to learn user interface, at least to
gain "novice" status. The more intricate commands become
more obscure, and less mnemonic. (Everybody agrees that
Meta-Control-single←character can get obscure).
"What-you-see-is-what-you-get" is Motherhood and Apple Pie
for screen editors, and EMACS definitely succeeds here.
The UNIX user interface is designed to save typing while
remaining reasonably mnemonic. A remarkable number of
"Advanced" users can't type very well, so this is laudable.
Unfortunately, this means users take a while longer getting
used to the command abbreviations. There exist variants of
the UNIX Shell (command interpreter) which accept abbreviated
commands and do other nice, user-helpful things (although the
"standard" (dumb) shells are more common).
Initial EMACS and UNIX users face much the same problem...
LOTS OF SQUINTY LITTLE COMMANDS.
UNDERLYING STRUCTURE: As I understand it, EMACS can
be thought of as having 3 layers: The user interface/screen
control stuff, the Macro level commands, and the macro
implementation level (Typically TECO). Certainly, the top
level is easy to use. The Macro level can usually be learned
and profitably USED by ordinary mortals, but the macro
implementation level (TECO or whatnot) requires a Wizard
to get good results.
UNIX can be thought of as a number of levels, nested:
The terminal driver & line protocol (control/s/q & "cooked" editing).
The Shell (command interpreter)
Programs (System commands & User programs have identical status)
The I/O Library (Buffering & simple file mgmt)
The System-Calls (Direct requests made to the UNIX Kernel)
While each of these levels may have some overlap and
inconsistencies, the general "clean" philosophy of having
only one mechanism to accomplish one result is generally
evident, and a real pleasure! [More on this some other day]
"UNIX productivity must be thought of, not in terms of lines
of code written per unit time, but in terms of lines of code
NOT REQUIRED..."
CONCLUSIONS: I feel that EMACS is one of the better screen
editors around, mostly because of the "macro" facility which
permits powerful features to be built on top, and I feel that
UNIX is definitely the best operating system that has surfaced
to date, because of the consistent system-call interface, and
the "Software Tools" approach to commands.
HENCE, I think that all UNIXs should have an EMACS, and
everybody should run UNIX!
-Mike Muuss
Ballistic Research Laboratory
PS: There exist EMACSs small enough to fit on an 11/34, and
UNIX runs on everything these days, so this is less of
a pipe-dream than it may seem!

I worked for a couple of years for Xerox on the Star product and
after this slanderous message I will no doubt never be welcomed
back. However I can't resist trying to shed a little light on
the confusing state of the Xerox office automation product line.
The key to getting through the Xerox propaganda is to realize that
there is NOT one, but TWO office automation product lines which
have been forcefully "merged." These lines were developed by two
competing groups and don't really have much in common.
The two competing groups are now both under the common banner of
the "Office Products Divison" of Xerox, and are attempting to
cooperate. But until a year or two back . . . well, I'll be
polite and just say that they were very serious competitors.
The older group is out of Dallas, Texas. The new group is split
between Palo Alto and El Segundo (both in California). Here is a
short table summarizing what I think are their main differences:

The human side of resuming something involves answering the
question "Now, where was I?". One very effective answer to
that question is the screen display of the task as it was
when you left it. (It is perhaps not the best answer, but
the best answer involveq some meta-knowledge of what you
thought you were doing and your intentions for the various
commands you had used. I am willing to assume that someone
can recognize what they were doing given the set of commands
they had issued before stoppingwork.)
I concur That the approach taken by the LISP machine and other
multi-window systems (that keep track of various process objects
and reinstate their displays when the oBjects are selected) is
correct. These systems typically provide two ways ob picking up
a droppedball -- by using a mouse tk select one od the objects
whose window is currently visible on the screen, and by using
a mouse to selecT an object from a menu window thatcontains a
brief description of each of the objects. The menu gives you
complete context for "where was A?" by showing all of things yoe
are juggling. This is very important becauSe the fewer details
you have to keep in your head about what you are doing, the more
head is left over for actually getting the work done...
Simply resuming a dropped activity should not be a problem
solving activity ("now, let's see, I think I had that running
as a kept fork under Hermes, which is running as a kept fork
under EMACS..."). The "multi-forking" TOPS-20 execs that exist
at several places (e.g. MIT, Stanford, Rutgers) also support
users who need to move "sideways" to do a task although TOPS-20
doesn't provide anything in the way of reinstating the display
context.

reasonable. For a workstation, I'm not so sure -- this
is a very special case. There are a relatively limited
number of types of things I am likely to be doing, and
each of them has its own intrinsic priority. When they
are interrupted, they carry with them an implication of
how soon they should be resumed.
For example, if I have to interrupt a phone call and put
somebody on hold, this is basically different from what
happens as I am going through my in-box and someone comes
into my office. Granted, I would like to keep track of
where I was both in the phone call, and in the in-box, but
my system should and could be smart enough to understand
the difference, and indicate that YOU HAVE SOMEONE ON HOLD,
TURKEY, before I finish the interruption and go out for a
cup of coffee. Incidentally, I have been know to leave
people on hold in just such a situation.
Also incidentally, I am not totally crazy about have

I am quite impressed with the degree to which you all responded
to my questions or thoughts on changing modes of operation in a
workstation to better reflect the way one does business.
Here is a scenario I would like to take you through. It is
about Debbie, an action officer in federal agency. Debbie
has an automated office. She has just sat down at her desk
(after getting her coffee) and is about to start her day of
work.
Debbie logs onto the system. Rather than being dropped at
operating system, she is dropped into the office automation
program (or shell). The first thing she sees is the top of
her desk on the screen.
There's an inbox, a notepad, a file cabinet, a phone, a
calendar, etc.
Debbie reaches for the inbox by either moving a cursor to
the inbox or typing "inbox". The inbox expands to fill
the entire display. In the inbox is a stack of messages
- visible on the screen. One of the messages is flashing
(or in a red envelope) indicating some level of importance.
Debbie reaches for that message first by pointing at it
with the cursor (or typing a command to read it).
The message requires a quick response. Debbie must gather
some information from several sources to answer the message.
One source of information is a phone call away. Debbie types
"desk" (or hits a function key labelled desk) and is back at
the top of her desk.
She then points to the phone and the screen fills with a
phone message pad on the left (to take notes on when a
call comes for someone else in the office) and several
phone directories stacked in the right hand corner. She
points to the phone directory labeled "DARCOM". She types
in the first couple of letters of the person's last name
(the person she is trying to reach is me - she does not
know how to spell Ivanciw - so she just types in "IVA".).
The phone directory opens to the first page with names
beginning with IVA. Debbie sees the number and dials it.
While she is talking on the phone she wants to take notes.
She gets back to the top of the desk and points to the
notepad. The notepad expands to fill the screen. She
types her notes on the notepad (which is really just an
editor).
At the conclusion of the phone call the she goes back to
the top of the desk and once again points at the inbox.
The inbox opens with the message she was last reading.
She realizes that she needs the info on the notepad to
answer the message so she types notepad - the screen
splits and the notepad with the phone notes comes on
the screen beside the urgent message.
Ah, yes, Debbie just realized that she needs some info
from the file cabinet. She types "FILE CABINET" or hits
a function key labeled "file cabinet" and a picture of
a file cabinet appears on the screen. She points to
the file drawer labeled "A-C" and it opens revealing 30
folder headers.
But wait, someone has just walked up Debbie's desk and
has asked if she had read the bulletin board this morning.
There was a notice about a presentation in the conference
room sometimes this morning. Debbie quickly hits the "desk
top" botton and points to the Bulletin Board in the corner
of her desk. The Bulletin Board expands and shows subjects
for 15 bulletins. One subject is "PRESENTATION" and Debbie
user points to it and the bulletin expands on the left side
of the screen. Sure enough, the presentation starts in 8
minutes! and Debbie wants to go to it!
Well, now she has to work quickly! Hitting the FILE function
key the screen reappears with the file drawer "A-C" open
showing the 30 folder headers. She quickly spots the file
she wants and using the cursor (or a light pen, or maybe her
finger on a touch sensitive screen) points to the folder.
The folder opens up to reveal 3 separate papers on the topic.
Once again she points to the correct paper and types "close
file". The file closes and she is back in the inbox with the
urgent message, the notepad, and the new file-paper all on
the screen.
Hell! the phone just rang and she is the only one in the
office!! She picks up the phone and finds that it is for
someone else in the office. Quickly she hits the DESK
function key to get to the top of her desk and points to
the phone. The phone expands to show a phone memo pad
and directories. She moves her cursor to the memo pad
and takes a message for her co-worker. She hangs up the
phone and types hits the CONTINUE button. (The phone
message is automatically delivered to the co-worker).
Continue puts her back into the inbox with her three
files.
She decides that she can't finish the message right now
so she hits the bye button and goes to the presentation.
Debbie knows that the next time she enters her inbox the
three files will all be there and she can dig right into
the reply to that message.
********************************
Notice a few things:
o She never had to give a command to run an editor or a
message system. She only pointed to a function and if
it used the message system it used it (INBOX) or if it
used an editor it simply used it (PHONE MEMO, NOTEPAD)
and never required Debbie to type MSG or NED or EMACS
or whatever.
o She was interrupted several times and had to move through
several systems. In all cases she never had to say
"suspend" or "save" - she just went to another function.
When she returned to the function she left it was right
where whe left it. Imagine somebody constantly clearing
off the top of your desk everytima you changed funcTions
- that is basIcally what we do in the automated office
tools of today.~∀4∀⊂∀*&C∃βπ⊗{[∃β≤≠↔;π⊗K=β'~β¬β∂}s∂↔C"βS#π α∩εJ≤z5β'~β∂?;≡K∪↔KNs≤4+Ns∂?Kε{CπSNs∃β'w#=β''→β/≠4K∂∃β∂+S?7∂#'?9∧+;['⊗{;7↔w!8$*εc↔πO*β3↔Q∧k∃β/v{]βg␈+IβSF{W∂#'→β?9¬##'Mε≠?;∂/βQ84Ph*Kπv#eα'6 ;∂'8h)55ji44(hP2OW⊗S↔∂QRα'[πv≠']∨~β'∪↔∂→↓≠

Sorry, Henry, but a capability iS NOT just a fancy name for a
pointer in a machine that doesn't have enough address space
to begin with. I Was referring to capAbilities in their full
encapsulation sense, such thatyou can only manipulate an object
if you have the rights to do so (encoded in the capability)
and you can only do it by invoking an appropriate entry in the
capability's type module. (This is only suggestive; particular
implementations differ, of course.)
No, some capability machines do garbage collection. Hydra did.
Lisp is not a capability machine. Lisp is just a low-leveL
language fora symbolic-object machine, and thus is attractive
to hackers( because theY can ergvel with arbitrary "addresses"
whenthey please (CADDADR, foR example.) Of course, no one in
Their pight mand would use Lisp that way tkday.

I can't help describing a Multi-window terminal program I wrote last year at
Stanford (with the help of Vaughan Pratt and Jeff Mogul). My reasoning was
that although "integrated systems" with menus and standard user interfaces were
desired in the long run, we needed a short-term tool to help develop such
systems. My program runs on the SUN workstation, which provides RasterOPs
on an 800x1024 bit screen at roughly the speed of 16 pixels/microsecond, and
computing power about 1/4 of a VAX-11/780.
The program has one simple function: an aribtrary number of virtual terminals
are displayed in arbirary windows on the screen. Each of these virtual terminals
may be to any machine on the local ethernet, or on the Arpanet (via a
gateway). Characters the user types get sent to the "current" host, (except for
one escape character used to enter commands), and characters sent from the
remote hosts get printed in the corresponding virtual terminal. When something
more urgent comes up, you just create another window (which can partially or
fully overlay the other windows), and when you're done you destroy that
window. At any time you may select any window to be "current", so there is no
LIFO restriction.
The important thing is that such a tool WORKS, and I find incredibly useful.
The virtual terminal uses ANSI standard escape sequences, so we can use all the
tools that have been around for a long time (like the SAIL Display Service,
Emacs under TOPS-20 or Unix, etc.) with NO modifications. We are planning to
use this to develop a more integrated system, but it is nice to have the power of
all that useful but obsolete software out there.

I must disagree. Putting phone messages for people in the same office
into the computer is extremely useful. My secretary mails mine to me,
so that I can review them either from home that evening or from
another site connected to the network.
This in turn raises a question. If I have an elegant work station at
the office with graphics and icons, etc., how do I read my electronic
mail from home on a cheap, slow terminal (probably 300 baud at best)?
Do I have to learn a whole different command language? Computerese
instead of pointing devices?

I see nothing unreasonable about entering something in the computer "for
someone in the same office"; I don't see that spatial proximity should
require using an alternate method of notification, assuming that the
mechanism is already satisfactory. If using little pieces of paper is
more effective than using the computer, this indicates that something
is very wrong in the design of the software. Either the software is
good enough to replace paper, which is presumably the intent, or somebody
blew the design. Thus, we have a very good way of determining if the
designers built a system tailored to human needs, or one which is simply
intended as an ego trip for the designer.
I still don't understand why people seem to think "rings" or "stacks" or
other complex connected graphs are remotely reasonable for representing
past context. The top of my desk has no little strings connecting all the
things I'm doing, and I don't miss them; if I have to deal with such a
mechanism on my computer, then somebody who wrote the software doesn't
understand how people do work. See above predicate test.
A more serious problem is, given massive amounts of state, how do you
preserve them over a system crash? In the case of distributed systems,
it is even harder, since the state may be embodied in many (potentially
unreliable) separate machines. In the best of all possible worlds, when
my personal workstation rolls in the door, I turn it on. If I turn it
off, the result of turning it back on should be to put me back in the state
I was in when I turned it off. Likewise for system crashes. If some server
somewhere crashes, this should be of no interest to me, even if I'm using
it; when it comes back, my work continues just where it left off. None of
this is easy, and some of it is probably impossible, but I think it is
important enough that we should be concerned about reliability at a level
above parity and disk scavengers.

The answer to "how do I read my electronic mail from home..."?
I have heard PARC aficionados say "Well, you WON'T work at home.
You'll be so much more productive during the day that you can
leave your work behind when you walk out the door." This position
does not constitute an answer to the problem. It is imperative
that we consider all modes of work in designing the next generation
of working environments. More people will start to work at home --
surely we have all heard predictions of electronic piece work and
cottage industry. More people travelling on business will be
carrying tiny terminals with them.
The question is serious. People have to think about how to subset
both the hardware and the software so that the essential style of
the interaction can remain. Of course someone working away from
their normal desk is somewhat handicapped now, but with good
planning (taking the right papers and materials with you) you can
write more on a plane than you can at your desk in the same
elapsed time. Workers whose desks are electronic shouldn't be
prevented in principle from having analogous benefits.

Such a protocol is, Of course, not sufficient to let you read
your mail elEgantly at home. What it requires is a system
(hardware and software) architecture in which the mainframe
is decoupled from the display. Fortunately this is a very
reasonable architecture even for the present generation of
workstations like the Star. If the display component and the
mainframe component are located close together, the bandwidth
between them will not significantly degrade responsiveness
compared to the present more tightly integrated architecture.

In response to your message of Tue Jul 7 22:02:18 1981:
The problem with spatial data organizations is that they are
really a class of menus, with the attendant problem that you
can not display every possible choice on the screen at once.
You can deal with this either by enlarging the data surface
(so that the user must move his window over it) or by creating
a hierarchy of spaces.
In either case an expert user will find that it takes more
time to locate a particular command than to type its name.
>From my own brief experience, I think that programmers would
find a spatial layout most useful for organizing short-lived
objects, like contexts. The feature that programmers using
our system like best was the ability to create a number of
such contexts and move among them - like having several

It was recently suggested (by Lawrence Butcher@cmu10-a) that
in order to manage a "deull of icon's what we need is a
global context/icon manager that understands how to organize
the icons on a desk. Several people have suggested that one
needs a hierachical, all-knowing, state preserving "assistant"
in order to provide uniform access, continuity across
interrupted sessions, and conformity across different users
kf the same desk.
It probably is my background in workstations (implementing
Smalltalk-80, a very distributed control machine) but
I have viewed the concept of a global organizer and
continuity/conformity enforcer as a mistake.
I see workstation developers and end-users developing zoo
of different types of icons. (The reason I say zoo is that
I see each icon behaving as an anthropomorphic instance of
a real-world tool). Thus secretaries, financial analysts,
accountants, managers and stockbrokers are going to run off
and create icons thatbehave like rolloindexes, memo-pads,
stock tickers, file cabineTs, bookshelres, steno-pads,
calculators, and waste baskets (one can even imagine someone
implementing the anthropomorphic method for hunting through
a waste basket, or even janitors who pick up the trash daily).
Users will create this zoo of icons becauSe they are familiar

I hadn't really thought about this before, but the PLATO
computer-based education system does exactly this - it saves
state between terminal sessions. It does this only for students,
though, not for "authors" (programmers). I hadn't thought of it
before because PLATO is so strange that I really don't think of
it in terms of other computer systems.
State-saving works but can't be done blindly. It turns out
that almost all real applications ("leqsons") require the author
to do his own state-saving so that the student doesn't coma up
with no context, but is instead presented with a higher-lEvel
frame that tellq him where he was and presents some options.
Only blind drill-and-practice stuff can use fulL state-saving
at all usefully, and sometimes not even then.

An interesting point was made about the necessity of being able to
conveniently hand-off a task to another person. Certainly it would
be simple to just dump the task's parameters from RAM to disk and
restore them again elsewhere. While technically feasable (I have
done that on my CT system to provide task interruption capability),
this is tantamount to scooping up the mess on your desk and dumping
it on someone else's. In any case the user iq probably going to
reoreaniZe it somewhat in order to make a smooth transition. Given
this, I don't think that special capabilities need to be created
to meet this "need" (I know that those of you using large central
αmachines may have dificulty with my technique depending on system
architechture).
As far as intra-office mail for phone messages is concerned, I am all
for it. I dislike being told that "there has been a phone message
waiting at the operators desk for you for several hours. Why don't
you ever pick up your messages ..." especially since I have been
waiting for the call and I happened to be away from my desk for two
minutes when it came. Paper doesn't hack it here.
There are some tasks that are very painful if you lose your work
because of system death and others that are unimportant. If I
have been editing a document for hours and I lose it all because
of a system crash, I am going to be VERY annoyed. On the other
hand, if I am reading my mail and the system goes down, it will
not be very painful for me to recover from that situation. We
are going to have to do serious study as to which tasks can be
recovered easily.
Convergent has come up with what I believe is a unique method of
protecting a user from a crash during an editing session. All
user keystrokes and the original document are maintained through
an editing session. If the system dies or ck in
time in my editing session, I can do a replay and watch the system
duplicate my editing session in short order. This is an interesting
approach and I have found it to be VERY useful (like the time someone
pulled my plug when I was four hours into an editing session ... ).

Reliable preservation of large amounts of state in the face of
hardware failures is a topic which has been explored extensively
in the data base world. (This is a nice example to support my
contention that the present tendency of computer science to fragment
into subspecialties is to be deplored.) Generally speaking, the way
to overcome the problem is ALWAYS redundancy. The forms of redundancy
that we have explored the most are (1) thinking of the workstation as
a cache for "truth" embodied on a remote file server, or (2) logging
important state changes on a server so that the workstation state can
be reconstructed (possibly slowly) if a crash occurs. A more exotic
architecture involving multiple copies and voting is explored in a
soon-to-appear thesis by Dave Gifford (MIT). The bottom line is that
the technology is available, if manufacturers and software houses
choose to offer it.

I have contended for several years that I don't need better languages,
compilers, or editors NEARLY as much as I need a database management
system. Alas, the conventional DBMS is oriented to social security
records. I once mentioned "well, you put all that on a database"
to someone and they immediately began to explain how they had
variable-length text which a database system "couldn't handle".
Of course, a large class of uninteresting systems think in terms of
fixed-length records, but what we lose by ignoring them is that they
solve a whole lot of other problems. I once worked in the "real
world" on a banking system, and it is a good way to learn to be
paranoid about hardware and software. When you start playing with
millions of dollars of real bucks, and find that people audit their
checking accounts (and even interest on savings) to the nearest penny,
AND your company has posted a mongo amount of dollars in bond to back
up their promise that they WON'T screw up, you find that redundancy is
a way oF life. DBMS systems havE all had to deal with this class of
problems; the fact that their image of the data is prehistoric does
not invalidate the other solutions.
From a personal workstation viewpoint, the problem is to implement
the redundancy oF state ata very low cost. If my machine crashes,
I want to boot it and get the display looking just like it did
before the crash, having lost perhaps a few small edits, or the
mail message I was composing (if it was shorter than some low
threshold) or possibly the window I just the instant before had
brought up. Doing this cheaply requires ingenuity.

Some of us already *do* work at home, and the receipt of stuff
that shows up in my office inbasket is a problem -- I have to
go in and get it periodically, or else have it batch-mailed to
me (the Post Awful actually does pretty good work here - I get
everything the next day).
At home I have a pretty nice workstation, but on a recent
vacation trip I Took a TI745 with me, and found it not nearly
as useful as it had been when it was my *only* terminal. My
work methodolkgy has changed so much due to the availability
of the woristation that it has become almost impoSsible to
gat my wori done with a Terminal with lesser capabilities.
My eLectronic "filing cabinets", etc., are optimally organized
for a windowed display, and have become extremely difficult to
use from a TTY or simple scope.
IT so happens that my workstation is relatively dumb (using
its internal microprocessor to handle NVT requirements only),
but the next generation should be quite intelligent - maybe
being my prime "host" itself. This all points up two problems
very neatly:
1. I need a portable workstation (or portable terminal that
can access my workstation);
2. If I use a portable terminal, then I need access to my
home workstation (the future one, that will be a
standalone system). This future system must be capable
of two-way communication; it can *not* be used strictly
to dial out to other hosts. It has to be a full host
in that it must be accessible from a remote user, and
probably from remote hosts and other workstations as
well. (gee, sounds like I just read RFC 782)

It sounds as if your problem is similiar to (and can use)
distributed database technology. The icons can be viewed as
tuples in a relation (of work to be performed, status of work,
worker, what have you). Some icons would be provided by the
system in a common format, others would be customized by each
user, probably using some menu driven options package although
for "sophisticated" users I suppose full programming might be in-
volved. The basic idea would be to have all nameable items
stored away on disk with their requisite status information.
This would preserve state info over crashes of the individual
workstations, but does not solve the problem of going to a new
workstation id your desk dies for a day or two.
In a distributed data base it has long been theorized that redun-
dant data will provide better reliability over crashes, machine
outages, etc. and provide some (possibly limited) data to the
User even if their home system is currently unavailable. Of
course this is a pain, because you havE to work up protocols to
insure that the data items all stay consistent with each other
and use up lots of overhead timastamping messages or locking and
unlocking at foreign sites to update data and it is sTill all
very, very SLOW! The fact that Ethernet has a higher data
transmission rate than the ARPAnet and that the updates may have
simple enough formats to use coding schemes will help. But i
suspect that this will still eat an unacceptable amount of com-
pute power at task initialization and termination. Update trans-
actions are where redundancy hurts most.
Distributed databases are only partly understood. One probled4ASf~)S\AI∃GSIS9NAQ←\Ai↑AMaYSh↓k`Ai!JAICQB\@A¬\A←EYS←kf↓iKGQ9SckJ↓o←kY⊂~∃EJAi↑@↓gi←e∀@AiK5aYCi∃f@@A→←d@@↓CYX@AG←[5←\@@↓SG←]L@@ACP@@AK¬GP~∃]←eWgQCiS←8←gSi∀@AC]⊂@AYKPAKCG AkgKHAaSG,AoQS

we will have to develop a new set of icons to define the new

the existing mental correlation between picture and function?
Perhaps we should look at the whole problem from another angle.
Let us assume that the "intelligent desk" leads us in the
direction of modified worker activity. I think we should do
another system analysis and see if we can come up with a new
view of the problem: one that has an elegant [simple] solution.

Assume the following:
A series of transactions is required to generate a consistent
database.
The cost of repeating a transaction is outrageously high.
The cost of restarting a series is even higher.
The cost of saving state at the client so that the series may
be continued is negligible.
What is the cost of the mechanism that guarantees that enough
state is preserved at the server to continue the series of
transactions given that either the server or the client may
crash?
Assume that the client, when resuming the series, may elect
to "continue" or "abort". Assume that "abort" is a truly
rare occurrence.
This is my image of the requirements of, say, a crashproof
editor that will lose no more than one keystroke if either the
client or server crashes. Note that although the "database"
(file being edited) is in an inconsistent state (relative to the
desired state), the user wishes to resume editing at the nth or
n-1st keystroke. Thus, viewing the user as the "client" and the
editor as the "server", the cost to the user of remembering which
keystroke came last or will come next is negligible. As we move
further back in time, the cost of restarting the series becomes
higher and higher. Assume for values of time > 10 keystrokes
the cost is nearly infinite. As far as I can tell, transactions
do not allow state to be SUSPENDED; they only guarantee that
under one definition of consistency, the state will always be
consistent. For a workstation, the two states in question are
The state of the workstation and the state of the work. Any
time the workstation state is consistent, the state may be

You might have noticed that some of the touch panel notes pointed
out the semantic poverty of a touch when compared to the multiple
selection buttons on a mouse. That difference holds wherever the
touch panel is mounted. It means that touch panel driven systems

Again, random assumptions are being made. Who says you can't
mount buttons where they can be used easily with a touchpanel?
Specifically, you can take advantage of the normal use --
pointing with one hand while the other remains in "home position"
at the keyboard -- to provide either mouse or touchpanel with
lots of "buttons" (just 'cause they have letters printed on top
doesn't mean they aren't buttons!). Of course, the kinesthetics
aren't exactly alike; but the assertion implied by JWalker that
mouse is necessarily better on this ground is pure assumption.
If there's evidence, tell us about it!
I didn't say there was no DIFFERENCE, just that the touchpanel's
inferiority as being asserted on unfair (scientifically careless)
grounds, that touchpanels were being castigated for faults they
don't in fact have. They are indeed different, and the good and
bad points of that difference need to be carefully explored
without the interference of preconceived conclusions.

Steve,
I was asSuming by Touchpanels that people mean those tpansparent
devices, or LED-matrix arrays, that get mounted on terminal
αscreens. I therefore don't see any distinction between the Bit
Pad One with a piece of hardware for the cursoR and the Three
Rivers touch-tablet which requires only my fingertip (except I
don't havE four buttons on the touch-tablet). The fine point
that touch tablets need not be mounted on the screen did not
escape me...in dact, I even cite the 3RCC touch tablet in an
earlier note.

Joe,
There is one real distinction between BitPad et al. and
sensitive-surface touchpanels, and that is the need or absence of
a gadget (pen, e.g.) that one must find and pick up (or take a
hand position on) before pointing/drawing. Is it your experience
that this is not important? I get *terribly* annoyed by the pen
on our Perq (which came with a Summagraphics tablet, not the
transparent touchpanel -- I don't know why). I think that a pen
on a cord is much worse than a mouse; what I don't know is whether
finding a mouse every time is worth having those buttons there
rather than (say) near the left hand. Have you experimented
with fully-worked-out setups that use each of the competing
technologies to its own best advantage? I really would like
to hear some information on this.

The reason joysticks are losers deals with the interaction
between the hand motion and the screen cursor motion. In
fact, it takes a lot of skill to convert a desired motion
on the screen to an appropriate nudge of the joystick. Thus,
joysticks usually result in a lot of "hunting" as the cursor
constantly overshoots the target and the user applies smaller
and smaller corrections to get it to land on the desired point
on the screen. See Stu Card's thesis; I know he presented the
reasons at his oral (I was there) and assume they are also in
his thesis.
I have no experience with tracking balls, and am currently
reluctant to offer opinions on them since I THINK I know a
very, very cute way to implement one...and I won't say more
until I've sold the idea.

Subject: Picture vs. Window names

Date: 13 Jul 1981 13:50:10-EDT
From: wilson at CCA-UNIX (Gerald Wilson)
To: works at MIT-AI
I think that the importance of worrying about the content of the
windows is closely tied to the nature of the working environment.
If the user is working with a relatively small number of windows
all of which have a fairly short half-life (probably no more than
a day), then having a nice window manager which just keeps track
by name is probably adequate, and certainly much better than
typical current facilities. I equate this solution to the ability
to declare multiple full-screen windows in EMACS, and then ask
about what windows you have created. This works nicely for me as
long as I chose good names for the windows, and I don't 'drift' on
to new things without closing out old windows.
The problem that is of primary concern to me is the environment
where a user has lots (probably hundreds over the course of a
year) of windows, many of which have long lives (> month), and
which are in various states of activity at any given moment.
When I handle this manually I often end up with a hierarchy of
storage and state preserving methods, with the "manager" being
a combination of paper and electronic messages and a mental
index. I find all the same problems that have been discussed
or alluded to in "works" messages:
* Windows change in priority and/or importance based on both
my own actions and actions of others. The biggest problem
seems to be that the actions of others can cause me to make
dramatic changes in my window organization, at least for a
short time.
* I can handle a handful of windows with little problem for a
moderate time. When the number grows I begin to lose track
of some. When the time period of a low priority window's
life is long, I also begin to lose track of it. This
corresponds to the usual observations about human memory.
* Almost invariably there are multiple relationships between
windows, and thus multiple organizations of the windows. A
single window name rarely means anything to more than one
of these views of my world. The key retrieval method is my
mental association between the window name and the semantic
aspects of the window that are of interest under given
circumstances.
* The window relationships depend upon not only the window
semantics, but also project priorities, personal preferences,
interests of the moment, machine availability, dependencies
upon co-workers, etc. Much of this meta-information about
the window organization is important to keep available, and
is used in developing priorities and schedules.
* When new windows are created I must thread them into the
existing structures, and also determine if any new structures
are required. The deletion of old windows may affect windows
not directly linked to the deleted window, as the reason for
the deletion may have implications for other windows not
otherwise related.
My conclusion is that if we are to use computers to maintain much
of our current paper files, we must provide windowing facilities
that are more versatile, more semantically oriented, and more
easily interconnected than the window naming and other similar
approaches would allow. I think that the use pictures, color,
shape, abstractions, sound, etc. are essential to this process.
They sure seem to help in manual systems, and I have not found
effective substitutes for many of them in my own limited work.
When talking with graphics people, they always use "icon" to mean
the 'total symbol', not just as the name of a region of the screen.
Although this does not imply that icon refers to any semantics, I
guess I havE felt that this is a natural extension of the grahics
term.

Phooey! This "endless hierarchy" of deletes is just plain silly!
Given delete and EXPUNGE, what if someone wants a file that has
been EXPUNGED? Should there be a little "Hardy Boys" icon which
given the burned junk from an "expunged wastebasket" icon could
re-construct (perhaps only in part) what was on the burnt paper
(the expunged file)?
And how about a little "paper shredder" icon so you could prevent
the retrieval of an EXPUNGED file? And if you didn't want to
trust your users to do that you could always have a bogus paper
shredder" icon which doesn't really qhred things$ but merely drops
them in the Wastebasket.

Subject: BitPad ExperienceKS at MIT-AI
We at DEC did not have mouse hardware on hand. What we did
have was a SummaGraphics BitPad with crosshair cursor that has
4 buttons (bugs in the PARC terminology) on top. It was fairly
easy to write software so that we could have a relative postion
mouse instead of an absolute location cursor. We even hyped
up the sensitivity of the mouse so that simple (wrist only)
movements could carry one across the entire screen. One can
even lift up the cursor and replace it like a real mouse.
Opinions:
Given the way the smalltalk window editors work, I can keep
almost all of my activity off the keyboard. Indeed I think
if I was given a chord keyboard in my other hand (5 buttons
could give me 120 different keys) then I could completely
get rid of that anachronism of the industrial age: the 4
row QWERTY keyboard.

The Alto set up has a mouse with 3 buttons ("bugs") for the
right hand, And a 5 key device for the left to play with.
There are text editors in Smalltalk that allow the mouse to
be used primarily as a pointing device while the key-set is
used to select actions and modes. So you see, devices exist
to keep the other hand busy also. I believe that Englebart
at SRI used a key set too. --Mike

to control cursor velocity or to move a previously delineated
region of the image around on the screen.
I think it might be most convenient to mount such a control on
the keyboard within easy reach of either thumb, such as on the
front edge of the housing below the space bar. One would then
not have to move one's hands at all to point at things on the
screen.
A much cruder device is available commercially. It is a linear
array of parallel electrical conductors. Stroking it produces a
bipolar analog signal. It is marketed as, e.g., a more rugged,
completely sealed replacement for a knob on a piece of military
electronic gear. Two of these could be mounted at right angles
to one another within reach of a thumb to control incremental
horizontal and vertical cursor motion.
Another possibility for minimizing hand motion would be to
incorporate a miniature 2- or 3-degree-of-freedom joystick
into the keyboard, in the form of one more, special, key.
Or even several such "joykeys."

Touch Panels! Touch Panels! Indeed. Give me the greatest touch
panel known to man, the Terminal Keyboard. Some of them even
come detachable.
Seriously, since the primary appeal for workstations will be to
users who already have some aptitude on computers, there should
probably be some correlation between touch panels and terminals.
(here I envision my briefcase-thin terminal with the touch panel
screen which doubles as a keyboard).

I recommend heartily that everyone stop wondering about window/session
managers until they read the four PIE papers now available from PARC,
by Ira Goldstein and Danny Bobrow. PIE provides most of the mechanics
for exactly the kinds of things people are meandering verbally around.
I'm referring to report CSL-81-3 from Xerox PARC. Also related, though
possibly not available yet, is CSL-81-4, ``PIE: An Experimental

There are many naive ideas for backup that work in limited
contexts. The assumption of keystroke backup is that the
keystrokes are the only information needed. That might be true
in simple system. It is not true when one is interacting with
a more general environment. For example, inserting files from
a hierarchy using names relative to the current environment.
Or reading mail, or waiting for timeouts.

You've fallen into the same trap that most people do. If what you
want is the ability to scan quickly thru a document, this suggests
that a capability the computer should have is to scan quickly thru a
document. If you want to make notes, the computer should provide the
ability to make notes. If you want to doodle in color, the computer
should provide the ability to doodle in color. What you've stated is
not reasons for retaining paper, but a specification of what
capabilities we need in a computer if we want paper to go away.
Now current technology makes a lot of this extremely difficult. For
example, at very slow data rates (say, 9600, which is as close to DC
as one would care to get), it is unreasonable to browse thru most
large documents. With 24-line screens, finding enough context to
make sense of what has been typed is nearly impossible. But saying
that online retrieval will never replace paper is silly; it means
you've failed to adapt the computer to what people need.
The observation that it is useful to print things out on paper so
they don't have to be stored online is likewise looking at the
problem from the wrong side. What I want is a method of taking silly
pieces of paper and getting them oNto the machine so I don't need to
store the paper! Fact: secondary storage is cheap, is getting
cheaper, and even primitive archiving techniques make iT look even
cheaper. Why should I have to do something (file a piece of paper)
that the computer can do more effectively?
I keep all my source listings in hardcopy form. Why? Because it is
faster to look something up on hardcopy than online. Why? because a
24x80, 9600 baud terminal is too small and too slow to accomodate me.
If I had four or five 60-line screens with a typical effective
bandwidth (including disk latency, etc.) of about 100Kbaud, I
wouldn't need to print anything. One way of achieving this is to use
multiple windows, but it is not the only way (another is to have four
or five 60-line terminals).
If paper is more effective, then there is a mismatch between the
needs of the person and the software. I don't see anything which has
yet made that statement even suspect. What we need to do is explore
how to eliminate that mismatch.

Date: 13 Jul 1981 10:35 PDT
From: Halbert at PARC-MAXC
To: WorkS@mit-ai
Here is a short description of programming by example. I
have gotten requests from a LARGE number of WorkS subscribers
requesting it.
------------------------------
Since a few people have mentioned programming by example and
the work I've done on it specifically, I will try to give a
brief outline of what it is, and what I've done:
At its simplest, programming by example is just recording a
sequence of commands to a system, so that the sequence can
be played back at a later time, to do the same or a similar
task. The sequence forms a program. The user tells the
system, "Remember what I am doing". The system executes
the user's commands normally, buT also remembers them.
The user has created a program by giving an example what he
wants the program to do. HoWever, the statements in his
program are the same as the normal system commands. The
user does not havE to learn some programming language with
its attendant syntax and semanticq; instead he can do his
programming -in the user interface- of the system, which he
already has to know anyway in order to operate the system.
¬
In addition, he has wpitten the program by performing,
concretelY, an example oF what the program iS supposed to
do. Since he can easily Verify whether he did his example
correctly, he can be fairly confident his program will work.
He does not have to understand his program abstractly.
Naturally, straight line programs without parameters are not
very interesting. Once the user has written a program he
may want to -generalize- it. He may want to print file Y,
instead of the file X he used in his example. So the system
has to provide a way for him to to change the constants in
his programs to variables, and specify how these variables
are to be bound (e.g. by prompting the user, by looking for
similar data, etc.)
The user may also want to insert conditional or looping
constructs into his program. There are various ways, which
I will not go into here, of inserting these constructs into
programs using programming-by-example techniques.
I would emphasize that this kind of programming by example
does not use inductive inference techniques used in AI,
in which the user does several examples, and the system
inductively determines what has changed from example to
example (e.g. 1+2, 5+2, hmm, first operand must be a
variable; or a[1], a[2], a[3], hmm, looks like a loop
stepping through the array).
The seminal work in programming by example was done by Dave
Smith of Xerox in his Stanford Ph.D. Thesis. Gael Curry
did similar work in which the examples given by the user
could contain abstract as well as concrete data values.
Certain industrial robots can be programmed by example by
guiding them through the task they are to perform. Here
at Xerox, I have added programming by example to a prototype
of Star. The system provides program generalization and
an iteration mechanism as well as simple command recording.
I have written up this work and my ideas on programming by
example so far in a Master's project report done for U.C.
Berkeley. I intend to continue and extend this work into a
Ph.D. thesis.

This abstraction is critical in protecting users from file repre-
sentations, and I consider any file system which does not support
at least this form abstraction to now be hopelessly behind the
state of the art.
I hope to do some more research in this area in the next few
years. The Hydra idea may NOT be the best, or even close to
right, but it is a whole lot better than any conventional file
system.
(In Unix, it is possible to use pipes to provide the transfor-
mation; a filter converts a complex file to a sequential byte
stream. Alas, Unix does not provide the protection necessary
to keep any random program from trashing the file by THINKING
it is a sequential byte stream file. Nonetheless, their heart
is in the right place. This is one of the reasons I think
pipes are a winning concept).
(The message based operating system for Spice, called Accent,
makes it possible to build systems with this style of
interaction).

Subject: Making paper go away
∂16-Jul-81 1928 Vaughan Pratt <CSD.PRATT at SU-SCORE> Making paper go away
Date: 16 Jul 1981 1445-PDT
From: Vaughan Pratt <CSD.PRATT at SU-SCORE>
To: works at MIT-AI
If paper is more effective, then there is a mismatch
between the needs of the person and the software.
Joe's implication that any mismatch between people and computers
needs to be eliminated is similar to the attitude that gave rise
to the BART fiasco. This zeal to automate everything is misplaced.
Some products already do their job quite well. Paper, for example.
One thing I particularly like about paper is that I can leave
it on the beach while I'm swimming without being too concerned
that someone is likely to walk off with it. Is anyone willing to
predict which century will see portable computers able to compete
with paper as an improbable target of petty thieves?
A more appropriate attitude would be to keep an eye open for
opportunities where the computer can outperform the traditional
product. I suspect this is what Joe really has in mind when
he talks about automating paper. Paper has its disadvantages
as well as its advantages. Pen-and-paper is a poor medium
for speed of text input (many of us type twice as fast as we
write, though presumably not Steven Gutfreund, who says he
prefers mice and chordsets to 4-row QWERTY keyboards). Paper
is inconvenient to transmit, with a delay measured in days
rather than minutes. It is difficult to search associatively.
It does not lend itself to alteration. Making duplicates for
redundancy (e.g. guarding against fire etc.) is awkward.
Text and graphics macros (Letraset, stencils, french curves,
rubber stamps, etc.) are relatively inflexible. Conversion
to machine readable form is much harder than the reverse
direction.
The moral is that while computers outperform paper in some
categories, it is wishful thinking to imagine that it will
also soon come to dominate in all the remaining categories.
Needless to say, the moral applies equally well to other
products besides paper, e.g. BART drivers.
Applying this to AI, I would prefer to characterize AI
not so much in terms of passing Turing's test as looking
for additional human activities that lend themselves to
automation.

I suppose you've heard of the idea of putting 2GHz packet
transmission repeaters on every commercial aircraft? The idea
is that there is hardly a moment when there isn't at least one
aircraft over someplace in the U.S., so the number of times
you would find the global network unavailable to your pocket
terminal should be fairly small...and of course, if you are on
the airliner, you should be able to use the facility as well.

Over two years ago I spoke with the North American VP of
a large European airline, he was looking toward terminals
in the airplanes for both passanger use and for airline
reservations/info (because of the high degree of being late
screwing up large numbers of passengers schedules - let the
passengers change their reservations while circling JFK or
when making that suprise landing at Moline). His company
was also thinking of utilizing TELETEXT for reservations
in cities offering this service.

Why not on airplanes? Until the problems of electro-whatever
interference are more under control we won't be using terminals
on airplanes. As they explained on one flight I was on, the
kiddies couldn't use their electronic games because they
interfered with the plane's navigation equipment. So I think
it will be awhile before we beam communications out of the sky
to our home computers!

It is not difficult to develop a sympathy for the
earlier comment that it seems sad to adopt as a primitive
of the automated office all of the curious mechanism of
the traditional paper mill. Three ring binders, electric

callingcards.

My initial reaction to your scenario is that the idea of selecting
an operation is no different in essence from continuing a suspended
operation. E.G. selecting INBOX is exactly the same as continuing

context. This is an important distinction of course, being made
feasible by the new generation of hardware for displays.
One question though. This scenario description assumes that each thing
you can select has one "reason" for being selected. The INBOX being
selected means you are rummaging through it. Is this assumption likely
to hold? That is, will the reason for selecting something always be
unique or unambiguous enough that the right set of operations will
become available automatically?

I currently use a system that keeps track of the previous infile locations,
the previous file(s), and the previous programs/tools. It is very
handy to be able to do this, but it *does* have some drawbacks. One is
that there is a finite number of such things that can be kept track of,
so occasionally you lose track of the nth-back thing (the computer does,
anyway - you may still remember it yourself); the other main drawback is
that sometimes you *don't* want to keep track of everything you just did.
You can't win, really. Either the system tries to keep track of *everything*
and makes it really confusing to go back through the ring structures after
being online for a couple of hours, or the user must issue an
explicit command to either "save" or to "don't save" when interrupting to
somewhere else.

Congratulations. It seems that you have just discovered the paradigm
of the Xerox STAR and Negroponte's Spatial Data Management systems. More
likely you knew about them already. With a little improvement in
Xerox's software, this could be the substance of an ad for STAR!
THe problem, though, is the same as the one on my desk--it get cluttered
fast with incomplete tasks. If certain tasks have long time horizons,
and certain ones have short time horizons, the result is a mess. If the
priority is not correlated with time horizon (since in my case there is
always more to do than can be done, requiring that some things NEVER
get completed), then the pile gets deeper and deeper. So now I need
three dimensions, and a way to hand tasks off to others in a partially
completed state if it looks like I won't be able to finsih them.
How does my secretary extract stuff from my "automated desk" and finish
it when I'm out--or conversely, how do I or a temp deal with her "automated
desk" when she's sick?

As I mentioned befkre, the concept you mention is exactly the one that has
evolved atXerox over the last 10 years and is (I believe) iNcorporated in
the Star in a Form very similar to the one you envision. Of course, your
scenario Includes a good deal more "polish" than the Star in terms of the
system being more intelligent about the relative priorities, default
desires, etc. of the user.

In response to your message of Sun Jul 5 14:23:05 1981:
We built a system here for ARPA which incorporates
some of the facilities you describe in your scenario.
The system consists of a number of intelligent (8080-based)
terminals hooked up at 9600 baud to a PDP-11/70 running
Unix. The screen provides a window into a data surface
which contains icons of various shapes. The outlines of
the icons are made up of standard printing characters.
The user can scroll the data surface by pressing an arrow
key (8 are provided to allow diagonal motion) or an
outboard joy stick.
The icons are user-defined and can correspond to any
program runnable under Unix. To run the program, the
user centers its icon on the screen and presses an
"activate" button. Typically, the program to be run
is the Ned (Rand ->BBN) display editor editing some file.
The user can return to the top level via either of two
buttons - "deactivate" or "detach". The "detach" button
suspends the program and causes the icon to blink. When
the user again activates that button, the screen is restored
to its previous state. I agree that it would have been
better to make "detach" the standard mode, but this was
not practical under Unix with the implementation approach
that we had chosen.
We haven't tried the system in an actual office environment.
Programmers found it cumbersome because there was always a
Unix command that didn't yet have an icon, and they already
knew most of the command names anyway. It usually took more
time to scroll to the icon than to type its name. People
always enjoy the demo however, and we are still looking for
a place to try it out.

The Convergent Technologies system has the ability to change
the keyboard encoding and the font on the display. We have
experimented with AZERTY, Dvorak, and special purpose
keyboards. We have used the unencoded mode of the keyboard
to simulate a chord keyboard. The only thing we lacked was
a simple way to relabel the keys (do you havE any concept of
how difficult it is to make 98 little self-adhesive labels
and stick them on your keyboard every time you make a change?).
I would be interested in the re-label-able keyboard if you get

I have used a reasonably good tracking ball on a system that
did the automatic recognition of human chromosomes. Every
so often, the system would get confused and not be able to
separate two chromosomes that were, or appeared to be touching.
The ball was used like a scissors to cut the surface, so that
two disconnected objects appeared. Our ball was homemade, and
the most circuitous of cuts to be made in next to no time.
The principle used was that of extreme gearing down, so that
very fine motions could be made. For these purposes, the
thing was very useful. I'm not sure how it would have worked
for menu manipulation. We used the terminal keyboard for that.

I think that one would lose a great deal of the effect of "offline"
proofreading if the system did much of that work in realtime which
the text was being entered. The clearest argument against that type
of system is that you are supposing that the errors are entirely
detectable from PREVIOUS context. Why should that be so? If you
are not assuming that then at what point do you extract and test?
Coherence is not a clearly distinguishable effect atany given level
(sentence, pgh, etc). Additionally, coherence and intention are
understanding efFects. It is not clear that they can be extracted
without a rather fancy knowledge acquisition and utilization system
-- not to mantion a erammar and semanticq analyzer to front end the
thing(neither of which we are very comfortable with yet). Lastly,
more concretely, having a Lot of little aid demons around it Oiay to

Subject: Alternatives to making paper go away

An alternative to hierarchical file structures for quickly perusing
bulk data: We once tried to implement a fancy solution to this
problem on a rather fancy piece of VG 3-D graphics equipment. Hook
the Z axis into the velocity of a joystick so that the faster you
move the farther away from the text you get. [Actually it isn't
quite as simple as that -- there are various tuned lags that have
to be implanted in order to give the user a chance to respond to
the modifed view, etc]. The effect is that of flying a helicopter
over your text and automatically zoom down for a close up when
you've decided that you're in the right part. I have never seen
a device less fancy than the VG that can respond and redraw quickly
enough to do this properly. The VG is a very high speed vector
graphics display that isn't really built for text work. It has a
stylus pad/light pen/knobs/buttons/full+keyboard (sorry, no meta
keys)/ and the nicest vector display around but it's really for
pictures, not text -- shame about that. Anyhow, we started to
do this and I got sick of having to deal with Fortrash and the
VG internal coding language after about a week so it never "flew"
but it was a nice idea. The real advantage is in reviewing huge
chunks of text (like the Unix manual) that are in some order (say,
alphabetically) because the text is still in front of your face
but the letters are smaller (and you get more of them on the page)
when you zoom out.

Actually, your example is quite amusing. We were recently at a
conference at Pajaro Dunes. One of our participants was walking
along the beach during one of the interludes, and left his book
on the beach while he went into the water. When he came out, he
found that someone had stolen his book.
Yes, paper is more effective for some things RIGHT NOW. While I
don't believe automating blindly is a good idea, for most values
of use of paper I would prefer to use a computer. Even if I
produce hardcopy so it can be carried around, read on beaches and
busses, etc., I prefer to produce it via the computer. There are
lots of cases where paper is more convenient ONLY because of limi-
tations of the computer (e.g., 9600 baud slow lines). And when
computers will cost only $8.95 (or free with a deposit of $500),
there will be far less reason to walk off with one. We have to
quit thinking as if computers will always be expensive, and decide
what we can do with them when they are not. In fact, assume the
cost of the computer is ZERO. Now, what would you LIKE to do with
a computer? What capabilities should it possess at the interface?
Assume a communication cost of ZERO. How would you like to commu-
nicate with other computers? Now, at any given instant we have
to temper these ideas by the rather nasty fact that computers and
communications really do cost money. But that should NOT limit
our imaginations. A Dorado is a good example of what happens if
you let ideas not be limited by technology, and technology comes
along. Things which were unbelievably bad to run on an Alto run
just fine on a Dorado.
Don't tell me automating everything is bad. I don't believe it.
Automating everything INCORRECTLY is bad. I'd rather worry about
how to do it right, even if right isn't possible, than to not
think about The problem because this year's technology can't
support it.

The static structure of text rarely matches its "content",
except for artificial cases like program sources. Most
of the time, the salient features of a document, which
are the ones I'd like a structured editor to key on, are
dynamically defined by the reader. Until such a symbiotic
system is available, the artificially imposed structure
of the presentation is likely to impede comprehension,
not expedite it.
The alternative is to agree on a canonic form for a class of
documents, and for authors to conform their contribution to
the mold. This solution makes discussion of the canonic form
difficult, and is probably sufficiently restrictive to repel
prospective contributors on other topics as well.

As is often my occupation, I am indoctrinating a new user to
EMACS. She (factual, please do not accuse me of sexism) asked
after a couple of hours of EMACS-power, if it would be possible
for "it" ("The Computer", i.e. a program) to warn her while she
is typing a text, that she has used the same word repeatedly.
I pointed out to her that (a) many words in English repeat because
they are common (parts of the verb to be for instance) (b) some
words need to repeat, like "pathologist" because of the technical
nature of the text, and thus to chose between "facts" and "data"
in discourse might be hard, or to warn her that in the last two
paragraphs the word "experimental" had repeated 6 times might not
work. However, her problem is understandable in English terms:
she is typing up notes for a doctor. He wants to write "well",
which to him means not to repeat himself, which means not using
the same word over and over again, unless it is a technical term
(a distinction he may recognize but I am not sure). His hard-
working secretary is trying to help him, and now that she knows
how much EMACS can help her in just the typing up of his notes,
she is asking for what she sees as the next step, a program
to help her with editorial corrections... (i.e. "How many
times have I used "practical"... should I get out the thesaurus?"
-- next step of course is to provide the thesaurus, but let's
concentrate on repetition of non-common but non-technical words
in text).
Any thoughts on this?
And my comment, to everybody, "BUG-EMACS", and "Work Stations":
See, secretaries are NOT a sub-species of homo-sapiens, they in
fact often request the most sophisticated features from their
editors, justifiers, work stations, etc. In fact, some of them
are even willing to work on programming the features they want
(they do know the specifications, after all!).

I have for several years wanted to write a system with the goals
you described in your note to Bug-EMACS and WorkS. (No funding
has materialized though.)
Some work has been done on the problem by people at Bell Labs.
See the paper by Lorinda Cherry in the June issue of SIGPLAN
Notices. Still the real problems are those that you pointed
out. How can a computer know your reasOns for word choice?
What is it possible to do without trying to implEment a system
that"understands" free text? (Good writing is more a matter
of taste than of strict rules. Of course, if mediocre writers
follow a set of strict rules, they are more likely to produce
good writing than if they ignore the rules. Bqt That's part
of a different argument.)
I have afew EMACS functions thatwere designed to help in
finding and correcting common problems -- changing "which"
to "that" (if you care) and "may" to "might" or "can" (may
is ambiguous). I'd like to hear from other individuals who
have written functions to help with the job of writing as I
am working on a technical writing environment.

I feel that the pen-mouse-ball discussion is reactionary --
though many of the ideas are realistic and practical. But all of
them look back to non-interactive sensors of the past. Suppose
the terminal could SEE the user -- using a couple of little
vision-boxes. Then (i) it could watch your hands. You could
point to your icons on the screen in a really natural way. A
tracking cross would permit higher resolution, and the cursor
would move at a rate, say proportional to some power of the
distance between where it is and where you point. Then, one
could use some more AI to distinguish "intentional" hand motions
from tremors, etc. A smart such box could watch your eyes and
face, too.
If you like holding a pen, that too could be wireless -- because
the vision system would track its point. Such systems could work
in three dimensions. The vision box would observe your
eye-point. When you move your head, the various windows would
move in accord with 3-d occlusions, and this would permit more on
a cluttered desk than the usual methods -- moving your head a
couple of inches to the left would uncover the next layer below
on each stack -- etc.
Given a lot of R&D, such gadgets could be made in the next few
years, and would be as important as speech inputs. We need a
"terminal vision machine" project. Also, aren't the CRT schemes
rather reactionary, if flat TV stuff is coming in the next year
or two? Instead of vertical displays we can soon have (i)
desk-surface displays for near vision and (ii) wall projected
screens for far vision.

Ben,
I don't think it's a fair reading of the present situation
to suggest that computer centers are "going away" in favor
of personal workstations. A better view is that the computer
center is becoming distributed and more easily incremented.
A lot of this is dependent on the specific cost of providing
service in any given technology. Today's costs make it
relatively cheap to provide a noticeable amount of computing
power to each person in the form of an individual workstation.
This means that the cost of separate packaging is less than
the cost of multiplexing several users onto the same (large)
machine. It's quite possible for this to shift back the other
way, though not likely, in my opinion.
Several things do remain centralized, and properly so:
a) file servers, high-quality printer/plotters,
long distance communication;
b) maintenance;
c) system development (hardware and software).
Your scenario of using a service in Chicago with overnight air
service is not only reasonable but entirely usual. There are
indeed services that are expensive enough to absorb the cost
of long-distance delivery. Various forms of fancy printing,
as you mentioned, is one; transcriptions of stenographic tapes
is another. I'm sure there are others.
Getting back to individual workstations, my own view is they
offer one big plus and one important trap. The big plus is
that the economics of adding a new user to "the system" is
much clearer. The classical time-sharing environment essen-
tially forces overloading of the machine, and we commonly see
environments where only the trivial tasks can be done during
the day and the heavy-duty tasks are delayed until evenings
or weekends. Unfortunately, it's these heavy-duty tasks that
are the reason for the facility and the people in the first
place. (Yes, I know this can be seen as a straight case of
mismanagement. Nonetheless, it's where things are.) With
computation tied to terminals, it becomes essentially
impossible to add people without adding capacity. (There's
always the possibility of "sharing" workstations. This may
be useful in some cases, but it will be clear to all that
when a person does not have access to the workstation, he
does not have access to anything. Compare with today's
situation where everyone has a terminal, but that doesn't
guarantee access to anything substantive at all.)
The trap in all this is there is a far sharper limit on the
size of the task that can be carried out with a workstation.
A lot of important tasks use more of the cetral facility than
the nominal capacity that is being doled out in workstations.
That will mean that transition from a small task fitting on a
workstation to a larger task that requires a different machine
will be relatively painful.

Subject: keyboards should get changed, maybe
Marvin Minsky suggests that it is unimaginative to worry about
track balls and mice, light pens and touch screens, when visual
sensors can interpret your finger and eye motions so that you
need not lift your fingers far off the keyboard. Keyboard?
You mean the good old qwerty keyboard, arranged in 1873 by the
Sholes brothers to minimize jamming of the big lever arms on
the keys as they made their way to the platen? That triumph
of technology over common sense? Well, if you want to be
imaginative, why stick with qwerty keyboards?
The answer, by the way, is not to be found by simply rearranging
the keys. It turns out that qwerty is not so bad. The scheme
the Sholes brothers used to minimize clashes put the keys for
frequently typed bigrams far apart, meaning on opposite hands,
which we know today means faster typing. Lots of people have
fiddled with keyboard arrangements; its not worth the fuss.
Dvorak did a time and motion study analysis in the 1930's and
only improved typing speed by about 5% (some have claimed more
improvement; this figure comes from experiment, by computation,
and by a typing simulation program that we have developed). (In
similar ways, azerty and alphabetical arrangements don't lead to
much difference -- about 2 to 5% decrement.) And several studies
of beginners using alphabetically organized keyboards show no
improvement over qwerty. (Paper available on request.)
The current keyboard is hard to learn (several months to get to
speed), a surprisingly large proportion of people in this country
cannot type, and the top speed is limited by a combination of
physiological/anatomical factors and keyboard layout. Chord key-
boards, as used by court stenographers, go considerably faster
(they type syllables, with several simultaneous keystrokes), but
this takes even longer to learn (years), and it isn't easy to
decode as the users develop their own code for many words.
(On-line decoding can and has been done.)
BUT, why have 4 rows of keys? Why have a space bar that takes
up the whole row and is used only by the right thumb? Why not
allow upward movements as well as downward ones to be meaningful.
Why not allow multiple strokes to have meanings. Why so big?
The current size and the funny diagonal layout is determined
by historical mechanical constraints and violates the natural
mirror-image symmetry of the hands. Fitts law states that the
time to move the hands is linearly related to log(D/P) where
D is the distance to be moved and P the precision required.
You will gain a lot if the keyboard is made smaller and if
sloppiness in target location is allowed. Eliminating the
need to type RETURN on a line can speed up typing a much as
30% (our high speed films show the hand must distort itself
rather badly to get to the RETURN).
Would speech input be easier? Probably not, but a combination
of a sophisticated keyboard plus speech might be very effective.
How about tiny mice mounted on the keyboard where the thumbs can
reach them, or worn on rings, or available on a "roof" just above
the keys so that lifting the hands a fraction of an inch contacts
them. Or consider inserting the hands into gloves (wear your
keyboard) with touch and force sensitive fingertip sensors and
let hand configuration select the word and/or cursor placement.
And so on. The point is, it is time to change the keyboard,
and not just by rearranging the keys; that won't buy anything.

I'd like to preserve my vocal cords, thank you. Not to mention
the fact that not everyone has a private office. I can deal
with the clack of my officemate's keyboard and the hum of his
disks, but I don't think I want to hear him muttering to his
computer all day.
I think that something along the lines of what Minsky was
suggesting would be more appropriate -- we could make much
greater use of technologies that have been heretofore
reserved for the handicapped, such as breath control, eye
control, etc. Also, I really like the idea someone suggested
a few days ago of placing lotsa special input devices just
below the spacebar. I just realized thatmy left thumb is
\completely/ unused!

The general question of sneezing, etc., is interesting, and I wonder
if there is a nice theory of this: many interaction-devices separate
"pointing" and "doing". One positions a mouse and then presses an
action-button. This makes things clear to the computer, and protects
us from using signals than can be accidental. One does not often type
"DELETE *.*" as a side-effect of a sneeze.
In my vision, the AI sensing system gets better and better at telling
what you intend. In the first decade, I suppose, we'd be lucky to get
it reliably to tell where you're pointing, or what simple verbal
command you said. In another generation, it would be able to tell
when you're talking to IT, rather than someone else who just came in.
("What're you doing?" "Oh, just deleting everyone's files" -- meant
sarcastically, of course, but obeyed by the clever system.) As we
progress, the systems should grow better at telling what you really
want, and being sensible about which such intentions are plausible.
Of course, I don't believe that programming will become a casual,
natural language activity, because I don't think natural language has
adequate ways to describe an advanced programmer's intentions. (But
perhaps in a couple of generations a new order of procedural
expressiveness will indeed creep into everyday life!)

If we are willing to disregard cost for the moment, why not
consider pupil tracking technology as an input device. One could
simply look at the desired operation displayed on the screen and
perhaps confirm its selection by pushing a button. This certainly
eliminates the hand coordination needed for mouse input and the
sticky screen and physical exertion of the touch panel. Having
been attatched to a pupil tracking device, I realize that current
design is uncomfortable for the trackee, but I don't know enough
about the technology to throw out the idea.
Any thoughts?

This idea has always intrigued me, though it would make for
a rather expensive keyboard. Then when one wanted a new
character set, one would simply download a new set of keytop
images to the keyboard. No messy paper stickons; invent new
symbols; who knows what possibilities?
No, I do not consider a video display with a touch sensing

Gordon Bell has pointed out that disk drives and fancy printers
are about the only things left that havE economy of scale. You
might as well chop everyThingelse into little pieces, it makes
the incremental cost smaller.
As almost everyone on this list surely knows, comp center people
frequently tend to be power-mad, bureaurocratic, etc. Given the
choice, would you rather use the comp center or the CS department
machines?
When computing is relatively free, all arguments about wasted
cycles are bogus. You should think of your computer like your
car. Are you worried that you car is sitting idle all day
while you are at school or work? I'd think that you'd be
plenty worried if it wasn't. Are you worried that it isn't
being used at night? No. Same goes for computers.
To do fancy graphics, you need a lot of local processing due to
bandwidth. Once you do that, adding general purpose computing
isn't all that hard or expensive. If the graphics is done by a
general-purpose CPU, a la Alto, then the cost is essentially
zero.

Speaking of soft keyboards, I'm surprised no one has mentioned
an old idea that has been kicking around 5 or 10 years: an image
of the keytops can be generated on the display and then reflected
off a half silvered mirror that is mounted over the keyboard.
The user can see the keys (even when his hands are over them!)
with whatever labelling he desires, switched at electronic speed.
Furthermore the geometry is such that the user doesn't have to be
exactly "on axis" to see the desired image.
Of course, there are some drawbacks, but none of them seem to be
showstoppers:
1) a lot of expensive resources (e.g. bitmapped display &
memory) are given up to support the keyboard image. Also
the image on the screen surface itself is upside down;
2) the glass "shield" over the keyboard sounds awkward;
3) I wonder whether screen curvature, raster blooming, and
the like would make it hard for the keytop images to be
precisely aligned with the physical keyboard.

P.S. Allen Brown tells me that this concept was explored
by someone in IBM on behalf of J. C. R. Licklider
(Licklider @ MIT-XX). Forgive me if this is a garbled

At an NCC a while ago, I saw a terminal with a dynamically
lableable keyboard. The keys were arranged in a 10 x 50 matrix,
and had transparent tops. There was a mechanical (air-driven,
I believe) sheet feeder that could slide any one of about 10
different layouts under the key matrix. The particular layout
was selected by function keys off to one side, and it took about
1/10 sec. to switch, accompanied by some hissing and clunking.
It was not an entirely unworkable arrangement.

If the RETURN key is in the wrong place and the full-length

I saw your note about a keyboard tracking system. It
seems to me that the most convenient position for a cursor
control setup is just below the space bar on the keyboard.
A small trackball or joystick modified (or even a two-
dimensional slide switch) could be easily manipulated by
either thumb without moving the fingers from the keyboard.
I find that I always use my right thumb for spacing,
thus I guess with a little practice I could use my left
thumb for cursor control EVEN WHILE TYPING.

Keyboards: There was a LONG series of discussions on Human-Nets
some time back about Dvorak keyboards. If there are people on
this list who weren't exposed to that, maybe somebody with an MIT
account could run an editor through the HN archives and come up

appropriate as the list seems to now be covering alternatives to
the standard keyboard, and Dvorak has lots of supporting data
which was outlined in that discussion.

I agree with Donald Norman about re-examining keyboards. I
wasn't concerned with keeping hands on keyboard, because I
once learned some American Sign Language (ASL) and saw that
sign-language works quite well and could be quite fast --
provided the intelligent observing machine can keep up. One
learns a large lexicon of special words and symbols in ASL
and, when these fail one uses "finger-spelling". The latter
is lots slower than expert typing, to be sure. But this is
because one has to reconfigure the whole hand for each letter;
the vision machine could sense smaller finger changes than a
person could, I think. Then we could adopt Norman's idea
of using bidirectional finger motions, and little "chords",
etc. In the end it should be faster than typing.
Gloves and rings and things might do, but I think AI will get
around to making good seeing machines eventually, and they'll
do so many things that they'll be cheap. In the end, there
will be two or three of them inside the average typewriter,
just watching for paper jams and ribbon problems. After a
while, people will find that they don't need many of the
machines that the vision boxes were made to keep an eye on.

Along with the keyboard gloves you get a head-mounted binocular
display, as in the old Utah 3D system. Now you can not only
move your head from side to side to reveal obscured pages,
but can walk around your workspace and view it from behind or
underneath. If you're into such, the entire workspace can be
mapped onto the surface of your real desk, and there can be
simulated piles of paper that look like the real thing! To
focus your attention on one, just move your head closer to it.
If the head mounted display carries outward looking cameras
that can track your fingers (and microphone and earphones),
you could pick up and shuffle the simulated paper. In the
long run all this stuff should be integrable into an
eyeglasses frame.
It needs some kind of intertial or other navigation system to
make sure it knows where your head is to generate the appro-
priate view. With a Radio linkto a communication system and
a shaving mirror iT could be used as avideophone. OR a cheap

The advantage of realtima fixqps, or at least flags you can
confirm later, is that the typist can detect whether something
heesh noticed as a mistake was also noticed by the computer
instead of wondering for the next hour if the post-processor
will find it; if the computer flagged it, then the typist can
safely ignore it now, even forget it, because heesh will be
reminded of it later when making a big confirm-pass thru the
document.
The problem with TWENEX is its method of flagging errors in
realtime is obtrusive. It goes ahead and makes a mess, instead
of just brightening or boxing the offending misspelled word and
letting the user move the mouse back there later to fix the word.
(Of course this is because it was designed to work on TTYs and
Decwriters, not ALTOs and other graphics-mode displays with
massive display-computing power and mouse.) Perhaps somebody
with experience on Xerox-Smalltalk on Dorado could comment on
how Xerox-Smalltalk handles errors when manually typing in
commands (instead of using the mouse to select commands from
a menu). I seem to recall you type commands into a window
and can edit them to your heart's content, then when you hit
the activation button on the mouse they are parsed and any
syntactic error is flagged, and you can edit again and again
until the parser accepts it.
Right?

In-Reply-To: <[OFFICE-3]20-Jul-81 08:38:32.WMARTIN>
The Spice project plans to treat the local disk as a cache for
the central file system. Thus, primary backup is handled by
the same staff which backs up all our other systems. Local
disks will not have substantive amounts of private data which
is not replicated on the CFS.
In the case of workstations not on a network, if we abandon
such archaic ideas as single-task workstations, files without
timestamps, and similar absurdities, and produce some reasonably
intelligent software, a background task which does hourly, daily,
or as-needed backup to a floppy disk or other medium such as
streaming tape, occasionally prompting the use to insert a new
disk or tape, and which handles the grubby details of how to do
file retrieval in case a file restoration is necessary seems the
obvious simple solution. As I am currently thinking about having
a personal 68000-based system at home, which will not be on a net-
work, and cannot use CMU's machines for backup, this is one of the
first pieces of software I would build. My plans are to simply
assign ascending serial numbers to the floppies, and keep a file
(which is naturally backed up) which is a migration archive file
[CMU-10A users will recognize this as MIGRAT.DIR...]. Since all
REAL computers (not toy computers, no matter how powerful) have
date-time stamps which can go on files, the software architecture
is reasonably obvious.
Those ridiculous systems in which one can save or restore the
entire disk, but not do incremental save or restore, are not
worth talking about. I certainly don't want to reset my
entire disk to yesterday afternoon just because the system or
I accidently damaged one file.
More sophisticated applications, including large databases, need
more sophisticated incremental backup procedures. But these are
ALL OBVIOUS and can be ALL AUTOMATED. Using "clerical people"
or "professional people" means we've forgotten the best drudge of
history: the computer itself. The overhead on anyone to write a
serial number on an existing disk or streaming tape and insert a
fresh one is so small as to be unnoticeable. (Of course, I would
never consider the problem of "tyIng up the floppy drive" while
doing backup; floppies are not reasonable as secondary storage for
serious applications; they are far too small and slow compared to
even the current processors they are mated with. I consider a 10Mb
disk as small, but marginally acceptable, on a personal workstation.
24Mb is acceptable, 100Mb is reasonable. Floppies are at best a
cheap backup medium, not to be used for serious storage. I have
a small personal database which already exceeds 1Mb).

Another problem with the idea of reflecting images of keycaps onto
the top of the keys is that it prevents the use of a detachable
keyboard. Some human factors expert at NCC spent a lot of time
ranting and raving about how important detachable keyboards are.
Also, the natural touch-typing position would mean that (1) the
home-row images would be invisible because they would appear
on my next-to-last finger bones, which are angled back toward
the screen, and (2) for most keys below the home row, the image
would appear on my fingers or hands at such a distance above
the keyboard as to make the association with an individual key
rather difficult. This could even become a racial issue(!),
since presumably black people's hands don't function nearly
as well as projection screens.
All in all, if you really want to look at the keys, the key sides
are a lot more visible than the key tops, unless you're some kind
of two-fingered wonder at the keyboard.
I don't think anyone has mentioned the idea of burying a small,
high-density CRT inside the keyboard and then using fiberoptics
to route the appropriate portion of the image to each keycap.

Subject: Terminal Input Devices
It seems to me that the position of the operator's head is very
important in a scheme to reflect the key markings off a half-
silvered mirror. I have always hated things with half-silvered
mirrors anyway, because head positioning is so critical. Also,
it eliminates the possibility of a removable keyboard.
On another tack, I was discussing some of these schemes (boots,
gloves, rings, LCD keytops, etc.) with a friend here at DEC and
he was repulsed by them. He wasn't even interested in foot pedals.
Then again he has always worked for DEC (since leaving WPI), and
neither DEC nor WPI are exactly at the forefront of these ideas.
It suprises me that no-one has mentioned the possibility (seriously)
of mounting the keyboard on a (large) mouse. Mice don't have to move
a great deal to scroll the entire screen, and four mounted as the
feet of a removable keyboard could work nicely. They would need a
sticky surface and would have to require more umpf to push them (in
order to avoid false readings), but I think the idea is feasible.
For those of you in love with chord keyboards, you could mount a
mouse under one even easier.
If you think this is entirely ludicrous, I cast my second vote for
a trackball near the left thumb (perhaps cutting the spacebar short).
My VT100 does not insist that a distort my hand too much to hit the
return key (it is a selectric arrangement), and I would rather be
cursory with my left thumb. However, as my WPI/DEC friend points
out, it can be hard to use: he has a broken left thumb.

I find the backspace and escape keys even more awkwardly placed
than CR. I usually use ↑H in preference to Rubout or Backspace
because the finger travel is shorter and faster, but not all
systems treat ↑H, Backspace (which is usually ↑H but sometimes
sent as rubout, depending on your terminal) and Rubout
identically.

Better yet, we could construct a box that "listens" to the
user's brainwaves (or brainstorms, as the case may be...) and
figures out from that what the user wants to do, and does it.
That way, the user would be completely spared the tedious task of
pointing. And by using a little more AI, we could construct a box
that would figure out what needed to be done (edit reports, write
programs, answer mail, etc.) and would do it without any user
intervention at all. That way, we could get rid of "reactionary"
old terminals and perhaps with the user to boot!

Let me repeat some of the phrases in the replies to my query on
configuration.
From Steve Crockers message;
"the cost of the separate packaging is less than the cost
of multiplexing several users onto ... larger ... machine."
"things do remain centralized, an properly so: file servers,
high quality printers, long distance communications, ...
maintenance ... system development ( hardware and software )"
"classical time-sharing ... forces overloading of the machine
... this can be seen as miss management... with computation
tied to terminals it becomes ... impossible to add people
without adding capacity."
"transition from small task fitting on a work station to a
larger task ... will be ... painful."
From Hank Walkers message;
"disk drives fancy printers are about only things left with
economy scale ... might as well chop everything else into
little pieces, it makes the incremental cost smaller."
attributed to Gordon Bell
"center people frequently ... power-mad, bureaurocratic."
"are you worried about you car sitting idle?"
"fancy graphics needs a lot of local processing .. (then the
cost of) ... adding general purpose computing ...(is) ..
essentially zero."
Forgive me for the paraphrasing and quotation out of context.
I find quite convincing the point that baseline services; communi-
cations, graphics processing, and packaging make the marginal cost
of a substantial piece of computing power in the office trivial.
No ones seems to argue for the demise of the computing center, I
had expected people to argue it would be replaced; on the low end
by work stations and on the high end by external service firms.
People seem to believe that central facilities, file servers etc.
will remain within the organization.
As an aside the comment about cost of multiplexing into the central
facility seems odd considering the huge increase in cost of communi-
cations that local networks imply verses front ends. Any one want
to argue the other side of that one? No one has explained to me
yet why the hugh bandwidth is a good thing in the local computing
environment?
I have believed that the leverage available in purchasing larger
machines was very substantial. If I build out of a fast expensive
technology I get a power of ten improvement in my cycles for a
linear increase in my cost. If I build out of many processors
I get a linear increase in power for a linear increase in cost.
Have I been stupid and mislead?
If this is true than, disks, fancy printers, communications, and
fancy processors will go in the central facility. The work station
design will be aligned on a cost effective boundary one up from
that amount of power necessary for graphics, communications, and
work space management.
I find the comment about cars rich in metaphorical implications;
there are many people who believe that cars are a very poor piece
of social engineering. Do organizations have more capital tied
up in the parking lot than they do inside? Unsafe at any speed?

What about the programmer? Source level Debuggers, complete control

latched to the on/ofd switch)?
Screen this, and menu that.
Will there be standards for screen definitions? Not at all
unlike the Core←graphics←standard we are seeing now, thanks
to VanDam and Badler and company.
Will there be "drivers" for One-User software? Distributed
power, shared computing, the questions of Queuing processes
accross machines - across the country.
Local-vs-Long Distance networks. How does one effectively
integrate this? There are more machines out today than ever

The above are just some thoughts/interesting topics to get

Joe Newcomer raises a very good point in his letter of July-22:
I find that I have less and less time to worry about,
say, how to make CR in EMACS behave like LF and how to stop
LF from behaving differently if the previous line started at
the left margin. I know what effect I want; I don't want to
know about 37 different variables, TECO FS-flags, and other
crap to get a simple change in behavior. This is a lot of
what is involved in getting really good personal workstations;
if I have to remember dozens of incantations to, say, set up
defaults when I boot, I'm not going to be very happy.

Peter Keene (sp?) of MIT Sloan School has a nice way of describing
the sort of system behavior Joe is looking for: mundane.
If I am not a car wizard I want my car's behavior to be mundane.
I want my car to be boring, I don't want it doing interesing things
like losing wheels. Many car drivers also don't want to learn all
the exciting things that you can do with manual transmission, boring
old automatic transmissions are good enough to get where you are
going.
If I am not a phone wizard I want my phone to be mundane. I am
not particularly interested in the intimate details of the phone
billing system when I am complaining about a $7,000 phone bill,
I really wanted the phone company to do the boring old thing and
bill me my normal ammount.
I believe that most people will want their workstations to be
mundane. They probably won't want a 3 week training course to
learn all sorts of wizzy neat features. If it behaves mostly
like those boring old office equipment (typewriters, phones,
etc.) it will probably be enough. After all, most people will
be using the workstation as a tool to get their work (what they
find interesting enough to be paid for) done.

Shade and Sweet water,
But designing systems who's most inexperienced user is it's
lowest common denominator severely limits what can be built in
to the language.
As an example, I am currently involved in moving Scribe
to the Lisp Machine (albeit, in a greatly changed appearence).
A decision that was made very early was that although the
DOCUMENT (the Scribe input file) requires no specialized
knowledge to write, extensions to the system itself require a
working understanding of Lisp, and the way Scribe works in this
version. The idea behind this was that if we tried to create
a "secretary extensible" environment, we would be sacrificing
efficiency (important in a package which is already dangerously
slow due to LISPM <-> PDP-10 I/O speed) and clarity of code for
the benefit of people who would probably not wish to change the
code anyway.
Besides, the typical supervisor doesn't want "low level"
personnel fooling with the code anyway. A friend who is
currently doing DE for DEC related the story to me of how her
supervisor had flamed when she had poked around the OS trying
to find out how to logout (it seems SOP was to hang up, which
she could not accept).

I was invited to Sperry's Software Research group and had an
opportunity to speak with them and examine some of the work that
they are doing in workstations and in programmer's tools. They
are more concerned with the "programmer's workstation" than a
management workstation and thus are putting a lot of effort
into the language that controls the device. It is designed to
be modified by the user and has inboard multitasking and file
system, etc. Understand that this design is for a device to be
hung from a large central machine for program developement NOT
for execution of programs. Here is a short list of the things
that (I saw) that they were thinking about/working on:
1) Pascal debugging/programming aids. They have a really nice
design (and partial implementation) for a visual program stepper
that draws colored boxes around the program structure and then
highlights the lines as they are executed so that the programmer
can "see" the program in exectution. It (will) also display
the variables and structure nicely. I played with this and it
made it very very simple to visualize what a program was doing
(especially when you turn the speed up fast enough and can see
where the loops are crunching along). The final implementation
of this should be very nice. [Jim Gimple (formerly a Snobol
afficianado from Bell) is doing this work].
2) A high res/color PWB system with joystick and mouse. They are
spending a lot of time working on the "editor language" (which
is also the JCL and workstation control language) rather than
"cutsie" features to add to the user view. The file structure
is Unix based but they ALSO feel that unix's user view is a
total lose and are designing one of their own that, from what
I saw, will be much nicer. Again, their position is that this
will be used by programmers, not managers or secretaries and
they are giving the user power to change things (in a properly
controlled manner) at whim without too much work. Currently
they are having trouble with the Univac hardware research
people (it's too slow for them) but that should be resolved
soon. This project is under control of Marc Fogel and Ira
Ruben.
3) Help systems. Knoweldge based and natural language driven (if
you like) user aids for the station command language etc. They
have several NL and AI people very interested in user assitance.
I don't know how/if this relates to the workstation but it was
interesting none-the-less. This work was being done by Nathan

Subject: INFORMATION RE INTERLISP DOLPHINS
Ed Feigenbaum received the following message from Mr. R.E. Bomeisler,
Marketing Manager for Xerox EOS, in response to repeated requests for
more information about Dolphins necessary for planning acquisitions.
Since others may be in the same situation, Ed wants to pass the
information along to other computer scientists. You may forward
it if you wish.

"In our telephone discussion, Ed, you indicated that Xerox
was not providing you and potential users with enough information
to assist you in designing your networks and planning for future
growth. I would like to apprise you of the steps we have taken
at XEOS to fill the information gap.
Marcel Pahlavan is the program manager and is the focal
point for responding to customer inquiries on interface and other
technical matters. On August 1, Terry Haney will join the staff
to provide hardware expertise. An Interlisp software expert is
being actively recruited. In addition, Pahlavan can call on other
system experts within XEOS to solve specific customer problems.
With regard to 3M bps Ethernet networks, the 1100 system
includes the hardware necessary for connection. In addition,
XEOS will make available the hardware necessary to connect the
DEC Unibus. This includes the DEC Unibus Ethernet Interface
Board, Transceiver, Terminator and Connector. This hardware
enables connection to 3M bps Ethernet on the DEC PDP-11 family
aswell as the DEC 2020 and the VAX family. To connect the
DEC 2040, 2050, and 2060 to 3M bps Ethernet will require either
development of a Massbus Ethernet Interface Board or a PDP-11
front end interface. When either of these is developed within
the ARPA-sponsored research community, XEOS will facilitate
distribution.
XEOS is a systems organization with the skills to develop
special hardware or software. It is expected that we will be
called upon to modify the 1100 hardware or software to meet
special customer requirements.
With regard to DEC hardware/software, there exists within
the ARPA research community a number of special systems. Many
of these exist on your own campus. As we become familiar with
thesesystems, XEOS will serve as a facilitator and will make
certain that potential 1100 users are familiar with interface
software that exists or is under development. To the best of
our knowledge, the following systems have been or are being
connected to the 3M bps Ethernet: KI-10/TENEX, KL-10/TENEX,
2020/TOPS-20, 2050/2060/TOPS-20, and VAX/UNIX. XEOS will
facilitate distribution of the Stanford-modified PUP software.
As you know, this software runs under TENEX and TOPS-20 and
enables DEC KA-10, KI-10, KL-10, and DEC 2020 to act as file
server to the 1100.
The dissemination and distribution of information would
be greatly enhanced by formation of an 1100 users group. XEOS
is prepared to assist in the organization of such a group.
XEOS plans to make available the necessary hardware and
software to connect the 1100 system to the 10 M bps Ethernet,
thus providing access to the Xerox 8000 Network System. We
are also investigating the feasibility of an internet gateway.
With regard to 1100/Interlisp performance, continual
improvements are being made in the code. The system is five
times faster than it was a year ago and significant further
improvement is expected.
Since the 1100 is a powerful, flexible machine, it can
be expanded in a number of ways: physical memory from 576K
words (1.15 M Bytes) to 768K words (1.54 M Bytes), virtual
address space from 4M to 16M words, and increased local disk
storage capacity. Furthermore, there is sufficient cabinet
space to add special functions that might be needed by certain
customers: floating point arithmetic, color display interface,
image processing, and other special logic, etc. XEOS is inves-
tigating the feasibility of adding to the 1100 system: color
display, low cost bit map display, large capacity file server,
and 5700 electronic printing system. The architecture, I/O
structure, and bandwidth of the 1100 make it the ideal machine
for dedicated applications in the research and scientific
environment.
In addition to Interlisp, XEOS is planning to implement
Smalltalk on the 1100. The schedule is yet to be determined.
As a key ingredient of the overall 1100 program, it is
planned to release a version of Interlisp on the Star processor
after January 1, 1983. This will provide Interlisp to future
users on a very cost-effective basis.
I trust, Ed, that this information will enable you and
others to plan system expansion."

Subject: "mundane" systems
∂26-Jul-81 1553 Jan Walker <JWALKER at BBNA> ''mundane'' systems
Date: Saturday, 25 July 1981 15:59-EDT
From: Jan Walker <JWALKER at BBNA>
To: WorkS at AI
I have to voice my strong support of Joe in his message against
"mundane" systems. The original message advocating mundane
systems used an analogy of a car -- you choose a boring automatic
because you don't care what wonderful things you might be able to
do with a standard transmission. Let's point out a few things
that make this analogy somewhat less applicable to the current
case (system/software design).
Notice that with the kind of technology people are accustomed to,
once you choose one (automatic), you can't have the other
(standard). (This can lead people into defending their choices
with more reasons than they originally had for making the choice.
Some psychologists talk about related phenomena under "cognitive
dissonance".) With the kind of technology we use, you can either
follow the same design philosophy -- make things in a limited
number of flavors and make people choose -- or you can design to
support redesign by the purchaser. Surely with the flexibility
of computers behind us, we can do at least as well as the kludge
in the car that chooses 4, 6, or 8 cylinders depeNding on load,
mileage goals, or whatever.
People don't like the iLlusion of choice nearly as much as they
like havIng the choice. The reason that so far we don't find
ordinary people looking for software modifications is that they
don't expect to be able to have them. (The old technology of
course has molded people's expectations about the new one.)
While I am on the car analogy... I hear a lot about providing
systems for people who want to be able to use a computer without
any training or practice. How many people do you know who wanted
to just jump in and drive a car without any training or practice?
(Not many!) Why do you suppose that difference exists? Consider
that a car has one primary purpose -- transportation. They all
have standard components and operating procedures. Even people
who have never driven know a lot about cars, for example, that
they have a little slot where you put a key and turn it in order
to start the engine. The point is that cars are simpler in
purpose and operation than computers, yet people don't expect to
just hop in and drive away until they know from cars. Maybe the
real lessons in this analogy come from considering training,
learning, and transfer issues.
The ideal way to provide software is to offer something that a
new user who knows about the application of the software (for
example, editing, drawing) can start using it with the help of a
good summary and maybe 15 minutes of explanation. The next
hurdle to pass is in discovering that things can in fact be
changed. A well-designed and documented program helps you make
this discovery and then provides good support tools to help you
find out what it is possible to change and how best to do it.

From: Farrell at PARC-MAXC

cc: WorkS at MIT-AI, Farrell
In places, you simply misunderstood / misstated Bruce Hamilton's
position; in others, your positions are new (and interesting).
Corrections/clarifications:
Bruce demanded 56 Kbaud, not Mbaud. The 3 orders of magnitude
easily cross the frontier of available technology.
There are a number of "centralized" services besides
archiving/library: printing, mail distribution, gateways to other
systems & nets, to name 3. Note also that file storage is a com-
munication mechanism as much as a receptacle -- it is easier (&
more efficient) to store a large object in a commonly accessible
container or two, & pass a pointer, than to ensure direct transfer
from the source to each destination.
Your framework of workstation & centralized facilities is impoverished
(and I believe not justified by Hamilton's discussion): there is no
requirement that facilities be centralized; in particular, there are
good reasons for distributing different services (functions) onto
different servers (machines), and for replicating and distributing
servers geographically (minimize communication, limit loss, provide
convenient user access). Even with most communications involving a
server on at least one end, this distribution still requires high
capacity in the underlying medium. When the net (or whatever) must
also support frequent reconfiguration, you may as well provide that
bandwidth to everyone, so you don't have to decide in advance which
ones are going to be servers.
Probably derived from your workstation/centralized facilities
dichotomy (and maybe a little from Bruce's remarks), I think
you put too much emphasis on network (i.e. communications medium)
failures, when server failures are more of a problem. I derive
this from my experience over 8 years now with two networks, ARPAnet
& 3mb Ethernet. In each, I can recall 1 occasion when I noticed
thenet was down -- that is, that NOBODY could use the net. (I
know the ARPAnet went down regularly for new releases of the IMP
software, and I've heard of outages on both which I didn't happen
to hit. . .) Contrast this to many occasions when I couldn't get
at MACSYMA, or the Datacomputer, or print on Clover, or wasn't
getting my mail, or . . . . Few of us are so single-minded that
we can't work around loss of a server (which needen't even deny
us the service -- e.g. redundant printing/file/mail servers).
Your super-automatic archive to file server has much to recommend
it; two possible drawbacks are that data on my local disk is less
accessible than anything that has hit the net or been stored in
a file server (clearly, holes that should be fixed; but while
they're there . . . ), and such a catholic approach may require
more resources than justified (I suspect workstation time and
file server space are more critical than communications
capacity).

The second release of Apollo DOMAIN s/w happened as promised in
mid-July. Performance has improved greatly - cmd startup time
is (usually) instantaneous, cmds execute much faster (cp, for
example, is about 25% faster both for copying local-local and
over the network), and most known bufs have been fixed. Func-
tionality has also increase (although there's still plenty of
room for more increases...): there are a few new s/w tool cmds
(such as Unix-like sed, grep, macro processor), the display
manager (i.e., their full-screen editor) has cut, paste,
searches, and the user can access the display memory and
bit-mover.
In response to a query from the other week, yes, the Apollo
Users Workshop did take place at Brown on 21-22 June. Users
and potential users from: USAF Geophysics Lab, Bell Labs,
CaslTech, CCA, Computer Techniques, Cornell, Daniel Wagner,
AHarvard, IBM Cambridge, MIT, Mentor Graphics, Schlumberger
Well Services, UMass - Boston, UPenn, and Yale briefly
described what they are planning to do with their apollo's,
Dave Nelson and Bill Poduska talked in detail about the
company's plans for s/w releases and general growth, Kim
McCall from PARC-LRG talked about implementing Smalltalk
on an Apollo, and workshops were held about porting unix,
graphics, lisp, and tex.
The general reaction of the participants was that Apollo is
listening to its user community, which at present is primarily
CS R&D/academia. Apollo looks like it will be around for quite
some time, and will be emphasizing mktg for commericial world
(though they promise not to forget us CSers). Presently, the
h/w is quiTe solid, and most agree that The s/w is still about
a year away from being there.

Message-ID: <MS"5(1631)"11747606017.5.545.5372 at DEC-MARLBORO>
Conglomeration of responses to "How does a mouse work?":
Currently, a mouse is a small box with a fairly large (1-2 cm
diam.) ball bearing captivated so a fraction of it lies outside
the bottom of the box. As the box is rolled around, two wheels
positioned perpendicular to one another pick off the rotational
motion of the ball in their plane only (they slip in all other
planes). Hence we get two rotational motions, one for each
component of the two-dimensional motion of the mouse.
The direction and (over time) speed of the rotation shafts are
measured by disks attached to the shafts encoded with a gray
code, and read either photoelectrically (via led and phototran-
sistor) or mechanically (via brushes). The grey code output
might look like 00 01 11 10 00 going one way and 00 10 11 01 00
going the other, so we can tell the difference in direction.
Some historical information about mice, according to Bill Barns:
The mouse as originally invented by Doug Engelbart and Bill
Engliqh and patented by them (rights assigned to their emplOyer
at the time, Stanford Research Institute (now SRI International))
consists of two high precision potentiometers connected mechan-
ically to metal wheels with rather sharp edges, approximately 2
inches in diameter, and set at right angles to each other as close
as possible without touching. [This seems a kludgey way to get
this motion, because the pots would "pin" occasionally, eveN if
they were 20-or-more-turn.] The pots are mounted on a metal base
plate to which is attached a bracket. On the bracket there are
(in the original, and still popular configuration) three switches
which are tpiggered by buttons about 5/16 inch diameter [8 mm]
which rest upon spring metal fingers attached also to the bracket.
The bottom of the metal finger rests on the momentary-contact
actuator of the microswitch. This arrangement puts some "click"
into the feel. The switches typically are SPST with a common
ground so that for a three button mouse there are four wires for
the switches and one wire for the non-ground side of each pot - 6
total. The mouse wheel voltages are fed into an analog->digital
converter of about 10 to 12 bit resolution and at appropriate
times, some logic samples the digital value and does the
appropriate thing.
Engelbart lives on at Tymshare, and English went to Xerox PARC
and gave birth to Alto etc., (not sure iF he's still there).
Bill estimates the invention of the mouse between 1962 and 1967,
and *guesses* 1963/4.
By the way, I got several warnings about suits, patents that I
musn't breach, etc, which I condense below:
Patents to SRI and Xerox apply to a number of features of the
design. The Englebart/English Patent iq probably still in
force, and it covers both digital and analog mice, [I wac
warned to check the patents before buildingmy oWn. I really¬

The Commander or somebody at the command wants to try office
automation. Now they are unsure of its benefits so they don't
want to spend mucho money. The buy a mailbox on our DARCOM-KA
(LARGE MAINFRAME). With this mailbox they can experiment with
all the OA tools.
After a short while they want 5 or 10 other people at
their command or activity to get mailboxes so that they can
communicate via electronic mail. They buy more mailboxes
on the large mainframe.
Then it is determined that office automation is good for the
command. They make large scale plans to provide OA services to
100, or 200, or 300, or how-ever-many prople. At this point the
economies of scale move towards the LARGE CLUSTER machine. With
a large cluster installed locally, the command is essentially
running their own OA.
BuT soon they find that more and more users are demanding service.
Enter the small cluster. As one division goes from one or two
users (who were getting OA services on the larga cluster) to a
demandto provide services to 8 or 10 peoPle in that particular
divisiOn, a micro computer is installed in the diviSion to provide
those services (and offset the demand on the large cluster). An
example of this implementation is DARCOM Headquarters. We began
by buying accounts on the big DARCOM-KA (large mainfraee). When
Demand grew to 60 users we brought a large cluster into the
building. The number of users on the large cluster grew from 60
last Oct to 210 as of last week. We now have some 20 micros on
order. These micros will service 8-10 user each so we now supply
services to an additional 160-200 individuals. As folks move
off the large cluster to the small cluster there are more folks
wainting in line behind them for accounts on the large cluster.
This multi-level (of size?) architecture seems to be working
pretty well for providing services to our command.

As I said in a message to Human-Nets (once again, the two lists are
discussing similar things), I think a reasonably valid statistic
for keystroke monitors indicating performance of the secretary is
keystrokes per character in output document. This way the typist
that makes no errors will have fewer keystrokes (lower, better
score) than the typist that makes lots of errors to produce the
same document. This also takes care of the problem of a secretary
idling by typing jkl;jkl;jkl;jkl;jkl;. I personally do not condone
the use of keystroke monitors to monitor performance (I think that
management should not even be told the statistic is available).
This all asSumes of course thatthe monitor is on aword processing
system used primarily for word processing. Programmers shouldn't
be subjected to keystroke monitors (I am a little more vehement
about this; it hits home), and fortunately the statistic is harder
to generate for programmers.

Subject: Four Months with Two Apollos
We have had two Apollos at Harvard for about four months
now, and I have a few personal observations to contribute from
my experience with them.
The best way to describe them is as a state-of-the-art
product, with the emphasis on product. The Apollo seems to be
the best large-micro-based system available with a bit-mapped
display, Winchester disk, and high-speed local network. Since
it started a little over a year ago Apollo Computer has managed
to produce a very solid piece of hardware, and quite a bit of
software. We have had no trouble with the hardware, and the
software, while poorly documented and a tad flakey (we are a
beta test site), has been basically usable. The network file
system works, and, on our small network, file access is not
appreciably slower for remote files.
The Apollo is not, however, a state-of-the-art tool for
computer science research, nor does it claim to be. It is not
a Dorado nor a Star-with-Mesa. A lot of the folks at Apollo
came from Pr1me, and in order to produce a working, competitive
product, they built what they knew how to build for a market
they were familiar with (the engineering/scientific market).
The system was tuned for user programming in FORTRAN, not system
programming, with such things as interprocess communication and
software interrupts not supported. Now that its primary market
is academic, Apollo will put a number of these features in, but
system programming, and the kind of features it requires, are not
a fundamental target of the system software. The system also has
a rather unsophisticated human user interface. Some of this is
clearly a matter of time, but some things that I imagine people
at Xerox would consider basic, such as a mouse and non-confusing
windows, are not along yet. (The Apollo windows are confusing
because they are all full-screen width and bordered with a single
line, so it is difficult to determine which windows are on top.)
It seems that Apollo did not do a lot of research in designing
their product, but instead will be educated by their users.

Here are the results of the "Are you actively working on an
Office Automation system" poll. The results surprised me very
much. Here are some of the numbers:
Responses 32
Working on a system 23
Not working 9
The "Not Working" column also contains responses from people
indicating that they were simply implementing OA functionality
on their home systems (e.g. not for commercial sale/distribution).
That was a value judgement on my part and may not be valid.
There were many very interesting responses but in order to keep
this message short I will exclude most. Two immediately caught

... LRG, a group within PARC, has licensed Smalltalk-80 (the
only Xerox-authorized version of Smalltalk to be released)
to a number of micro- and mini-computer manufacturers. The
release consists of detailed specifications for the machine-
dependent kernel, plus a mag tape containing the rest of the
system (windows, editor, compiler, file system, etc., etc.)
Several of these manufacturers have made excellent progress
on implementing the system, to the point of having windows
appear on their displays. I can't comment on the specific
list of manufacturers, since we prefer to let them make
their own announcements. ... and we are currently working
out ways to license the system to manufacturers (and univer-
sities) beyond the original group. I can't comment on the
availability of Smalltalk for the Star, except to say that
the Star hardware is definitely powerful enough to support
Smalltalk.
-- <Deutsch at PARC-MAXC>
Smalltalk IS being released by PARC this summer. There
was a big presentation on the subject at this year's NCC.
Apple, DEC, HP and other companies are doing research
into implementing it on their machines. (In fact, one of
the primary Smalltalk implementors, Larry Tesler, is now
at Apple and was one of the speakers at NCC.) A huge
article on the subject will appear in the August issue
of BYTE.
The deal is that PARC gives you an "image" file on a
tape, which contains all of Smalltalk ready to run. To
run it, you have to implement an interpreter on your
machine for the 256 Smalltalk bytecodes. Just like you
can run Pascal, if you have a P-code interpreter.
-- Ron Newman <NEWMAN.ES@PARC-MAXC>
... Xerox intends to release a book on Smalltalk called
Smalltalk 80. This version of Smalltalk is intended to be
easily portable. There was some discussion within Xerox
legal about whether the Smalltalk virtual image would be
released. But the book which describes the interpreter
plus the virtual image would result in a very easily
portable language.
One could then port it to the machine of your choice,
including the STAR, assuming that you could PROGRAM
the STAR. When MESA gets released you will be able to
implement it in that: but a better place is microcode.
I haven't heard anything definitive about whether Xerox
intends to microcode the Dandelion (STAR workstation)
for Smalltalk.
-- Michael <mike at RAND-UNIX>
... Also, XEROX is now putting up Smalltalk on the Star,
for internal use. I have no idea, and I suppose neither
does XEROX, if they'll ever release it.
-- Chris Ryland <RYLAND at SRI-KL>
Ed Feigenbaum received the following message from Mr. R.E.
Bomeisler, Marketing Manager for Xerox EOS, in response
to repeated requests for more information about Dolphins
necessary for planning acquisitions. ...

"In our telephone discussion, Ed, you indicated that
Xerox was not providing you and potential users with
enough information to assist you in designing your
networks and planning for future growth. I would like
to apprise you of the steps we have taken at XEOS to
fill the information gap.
...
With regard to 1100/Interlisp performance, continual
improvements are being made in the code. The system
is five times faster than it was a year ago and signi-
ficant further improvement is expected.
...
In addition to Interlisp, XEOS is planning to
implement Smalltalk on the 1100. The schedule is
yet to be determined.
As a key ingredient of the overall 1100 program,
it is planned to release a version of Interlisp on
the Star processor after January 1, 1983. This will
provide Interlisp to future users on a very cost-
effective basis.

Many thanks to those who responded to the micro benchmark query.
I have summarized the benchmarks reported in the April 1/81 issue
of EDN, but the article should be read for details concerning the
benchmarks. It appears that the 68000 is the hands down winner,
unless you need floating point processing and can't wait for the
chip (floating point benchmarks were not performed in the report).
I have appended messages (edited to remove redundancy) from those
who responded to the query.
Benchmark tests were compiled at CMU in 1976, and coded by each
manufacturer.

Forest Baskett has the famous "Baskett Benchmark" that has been

and MC68000 in both C, "hacked" C and Pascal. The results
are very informative. I would like to see the results on other
microcomputers. By the way, we get almost 40% VAX/780 performance
on the 8 MHz 68000 in this test, which is a small, integer only,
compute bound puzzle solver.

From: CAIN at SRI-AI
Subject: Micro benchmarks
The April 1, 1981 issue of EDN has a number of benchmarks
between the LSI-11/23, the 68000, the Z8000, and the 8086.
They are taken from a more complete study done at CMU which
I was hoping to find one of these days.
Since these benchmarks omitted floating point tests, I
performed a couple informal ones on a 68000 with Doug Beck
here at SRI. To do 10000 iterations of a floating point add,
subtract, multiply, and divide took 71 seconds (implying 1.75
milliseconds per operation) using Whitesmith's C compiler and
104 seconds using Motorola's PASCAL compiler.
When talking to Motorola about this sluggish performance,
they mentioned that the 68000 has a fast floating point PROM
in development which has done floating-point multiplications
(in software!) in 35 micro seconds. This compares very well
with the LSI-11/23's floating point hardware times.
Also C makes all floating point numbers to double precision
before doing the implied operation, meaning much of that 71
seconds was devoted in going "float-to-double" and
"double-to-float". According to my calculations, the 68000
is capable of that 35 microsecond time easily (roughly 100
to 150 clock states would be required), and since it has the
most support (cross compilers on the VAX, etc), I think it is
the preferable chip. It is promised that the floating-point
support will be built onto the chip mask so that some new
instructions will manipulate floating point numbers directly.
I am seriously weighing the choice of VAX vs 68000 for a new
project (where cost may outweigh the greater power of the VAX).

Business Day : IBM Personal Computer
By ANDREW POLLACK
c. 1981 N.Y. Times News Service
NEW YORK - The International Business Machines Corp., the
giant of the computer industry, is thinking smaller: Wednesday
it introduced a personal desk-top computer for use at home,
in schools and in business.
Although the announcement had been expected for months,
it still sent reverberations through the industry.
Besides representing a dramatic change in image for IBM and
marking its entry into consumer electronics, the endorsement
of personal machines by a company whose name is practically
synonymous with computers is expected to stimulate the growth
of the business.
And IBM could pose the stiffest challenge yet to Apple
Computer Inc. and the Tandy Corp.'s Radio Shack division,
the current leading vendors.
"It's one of the most important announcements we've seen
in the industry," said Christopher Morgan, editor in chief of
Byte, a personal computer magazine.
"People will now know that personal computers are not a fad
or a flash in the pan," said Michael McConnell, executive vice
president of Computerland, a chain of a retail stores that will
markat The new IBM products.

IBM announced its new 8080 based personal computer yesterday.
The prices range from $1500 to $6000 (approx.). It seems
that the system has color graphics* Does anyone has any
more details on the system? What is the OS on the system
and what are options?

Subject: Benchmarking new Micros
I forget where I first heard it said that benchmarking was Advanced
Lying With Statistics....
I looked rather carefully at the EDN benchmarks when they first
came out. I took these more seriously than usual because:
They were in Assembly language; therefore they measure
programmer skill plus machine performance, as opposed to
higher-level-language benchmarks which measure programmer
skill plus machine performance plus compiler quality.
(Worse yet are benchmarks written in different languages
for different machines which throw "language- quality"
into the mix... or benchmarks running on time-sharing
systems that end up measuring scheduler fairness and
disk performance.)
They were written by employeeq of the respective manu-
factqrerq who were likely to be skilled with the given
architecture. This also removes the possibility of
unfair advantage given due to hidden prejudices.
A reasonable covepage of routine typeq were made that
α colhectively might represent "general perforeance".
(Including interrupt service routines was a good movE,
for example.)

A salesman from Intel was here this week and said that EDN has
retracted its benchmarks and will run another set. He said that
the new numbers show the 8086 only 10-15% slower than the 68000.
He said the retraction would be in the next issue.

Subject: Re: Benchmarking new Micros
Worse yet, benchmarks can be doubly deceiving, since they
may induce you to choose a micro for all the wrong reasons.
Unless you have a very specific application in mind, or
unless you plan to design and build your own operating system
from scratch, software development facilities, system quality,
and especially user interface quality are extremely important.
A Dorado, for example, may run faster than greased lightning,
but it would be about as useful as an F-15 powered by turboprop
engines if it had IBM-quality software running on it. After
all, most of us do not want to write reams and reams of code
in some J-random processor's assembly language (more so if it's
microcodable); so quality of the high-level language available
and quality of the compiler ARE important. Furthermore, most
applications change, and even with changes, their lifetime is
limited, so that other development facilities (editor, debugger,
etc.) are ALSO important. If it takes you 10 times longer to
write a program that will take 10 times longer to debug and will
eventually run 10 times slower, on processor A whose raw speed
is 10 times greater than that of processor B, which one would
you choose? Choosing B will save you time, to say nothing of
frustration, even though it is a "slower" processor. These are
not idle thoughts: an IBM 370/168 has tremendous raw speed, but
some of the cruftiest software ever written makes it seem slower
than the US Postal Service. Admittedly, almost all of the
software for micros such as the 8086 and 68000 is pretty awful,
but I still think it's worth keeping the above considerations
in mind. As Allan points out, just because something is easy
to measure does not mean it's useful or even meaningful.

Subject: EDN benchmarks
Allan Schiffman may be right that the EDN benchmarks are
"about as useless as benchmarks usually are," but the MCF
(Military Computer Family) test specifications on which
they were supposed to be based *can* be used in a sensible
fashion to evaluate a computer architecture. The original
experiment design was set up at CMU with the co-operation
of one of the members of out Statistics department, who
designed the experiment to separate variance on the tests
into differences based on programmers, particular tests,
and the architecture itself. The notion was to see how
good the *architecture* (instruction set, visible registers,
etc.) was, rather than any particular implementation of the
architecture. Several different measurement scales were
set up. One measured the number of bytes need to encode
the programs, another measured the memory accesses needed
in an idealized implementation, and the third measured the
amount of data transferred between registers in the idealized
implementation. I'm a little disappointed that the tests are
being used now for a different purpose; it's not clear to me
that you want the same kinds of tests to do a comparison of
particular implementations of the architecture, as was the
case in the EDN tests.

For those of you who stay in touch by computer rather than paper
or radio: Here's the latest on the IBM PC. It's a three-piece
unit, VERY slim nice-looking keyboard, with basically the same
key layout as the 5250 series. The display looks cosmetically
the same as a displaywriter's, and sits on a logic box with dual
diskettes. Inside we have an 8088, up to 256K, five expansion
slots, 80x25 screen memory with graphics 320x200 or 640x200.
Figure it out, that means an OK but not great 8x8 character
cell. The unit displays up to 16 foreground colors on 8 back-
ground colors (but I doubt if all those are available in the
graphics modes). And you get a sound generator and built-in
speaker to boot!
The thing is totally modular; even the I/O cards are separate!
For $ 1,565 you get a keyboard and logic unit with 16K RAM and
a Basic interpreter in 40K ROM. A cassette interface is built
in, I think; but no diskette or monitor at this price -- you
use your TV set. Of course you can add one or two minidiskettes,
lots more memory (16-64k increments), a B&W monitor (no color
monitor was mentioned), RS-232C interface card, matrix printer,
a joystick/paddle interface (but you have to buy somebody else's
joysticks and paddles); and maybe the kitchen sink. A "business
configuration" with 64K, dual diskettes, printer, and "color
graphics" goes for about $ 4,500.
The big news might be the software -- there's plenty of
it. If you don't like their idea of a diskette OS or Pascal
compiler or word processor, you can try USCD Pascal or CPM-86,
coming soon from Softech and Digital Research. (Gee, and I
was looking forward to JCL). And then there's Visicalc, three
Peachtree business applications, Microsoft Adventure, 3270
emulation on the way, and a new IBM Software Publishing outfit
(!**8). It looks like they read Byte.
Where can you get it or ogle at it? Try your local Sears,
Computerland, or IBM store (or DPD sales rep, if you're a
big banana).

Subject: Micro benchmarks
This may sound like an answer that begs the question. But THE
one true way to benchmark a micro depends entirely on your point
of view. (As you see, I have an unmatched knack for discovering
the obvious.) CPU architecture and instruction throughput matter
the most to designers of CPU boards for number-crunching and other
compute-bound stuff. Good I/O architecture and throughput score
highest to OEMers of communications and data base boxes. Good
compilers, spiffy user interfaces, and software tools (Xerox we
hear you!) matter the most to the rest of us system developers
and end users. What you will "see" is what you should measure.
Just to be exhaustive if not obsessive, I'll mention the sometimes
overlooked importance of good I/O controllers and peripherals,
especially big fast disk; a W-I-D-E choice of hardware and
software offerings; reliability, support, and the prospects for
compatible future enhancement. Most of all, vendor credibility
and track record. How do I benchmark thee, have I counted all
the ways?. . .

Subject: NCC 1982 Personal Computer Sessions -- Call for papers etc.
The 1982 National Computer Conference will have a track (i.e.,
a group of sessions) on persOnal computers. This means that
the papers will be refereed and appear in the proceedings.
This is in contrast to pasT years in which there was a
separate, unrefereed "subconference".
This reflects the growth and importance of pepsonal computers.
But it is also a challenge. We must organize a new set of
sessions and get new referees. Part of this challenge is in
finding a balance between sessions on the mature areas in
personal computing and capturing the innovation in ongoing
research and development, both in academic and commercial
projects. Workshops might provide a better forum for the
latter.
Some of the possible topics include:
- what are personal computers -- the definitions range
from Alan Kay's dynabook, to miniature mainframes to
workstations.
- what personal computers are not.
- specific applications and issues such as wordprocessing
(though word processing also falls under office automation)
- Protocols and standards
- Networking as it relates to personal computers. This
can represent both local area networks as well as ad
hoc telco networks.
- Operating systems -- both traditional and new concepts
- Languages
- Consumer computers -- issues in design, implications of
a software marketplace.
- Education -- traditional and otherwise, computer and
noncomputer
- Implications and relationships to other fields both
within the industry and in the rest of the world.
Societal interactionals.
- Hardware trends and issues
- Games, both recreational and educational.
I am on the NCC steering committee and am in charge of
organizing/creating these sessions. If you have any
suggestions or comments, and if your are interested in
participating by writing a paper, refereeing or whatever,

Would someone collect information on the IBM Personal Computer,
and then send it out to the list? Here is all that I know about
it:
Processor Class: 8086 (lets face it, its a display-writer)
Up to 256 K memory
Either Floppy (avail now) or Winchester drives.
Can run DOS, a version of CP/M or IBM's own OS.
Will have EasyWriter & VisiCalc; not sure on Wordstar.
It is clearly going to be more powerful in the long run over
8080 class microprocessors.
For more info, they havE an 800/431-2670 number for information
pacquets.

Subject: IBM's personal computer: S100?
I saw a sales presentation and a couple of prototypes the other
day. From what I remember, the cards did not look like S100
cards. During the presentation, they promised to publish the
bus specs, so we can assume that it isn't S100. However, they
seem to be encouraging a plug-compatible market, so it should
soon grow to be as large as the S100 market.
Someone sent a message to this list some time ago describing
the system. I learned little of significance at the presentation
that was not in that message. I do want to clarify something
that could cause confusion. The DOS that is offered with the
personal computer is not the same one that runs on the main-
frames. If you think about it that would be very difficult
to do, but IBM hasn't been very clear about it. I am told
the new DOS is of the same flavor as CP/M.

From: Marc.Donner at CMU-10A
Subject: IBM Personal Computer
I saw some of the discussion of the IBM personal computer
in the ApoLlo bboard at CMU. I jusT left IBM Yorktown
Heights and I Brought with me a copy of the 'blue letter'
that announced the PC. I will be gla` to send you any
information from it that you want ... iT is public
information. I don't have it with me physically right
αnow, but here is some of the gist:
In the beginning IBM will be selling two basic configurations:
Configuration 1 includes 'System Unit', Keyboard, 48K RAM,
40K ROM, floppy disk controller and one floppy (5-1/4 inch
minifloppies). Configuration 2 is same as configuration 1
with addition of another 16K RAM (total 64K) and the other
floppy. The system unit has capacity for up to five cards.
One option that you MUST buy before you may use the system
is one of three video interfaces. One interface connects
to the IBM monochrome display, one connects to a TV modulator,
and one connects both to the monochrome display AND to the
printer. The list price for Configuration 1 is about 2300
dollars. For configuration 2 the list is about 3000 dollars.
Oh, one thing that is also included in the Configuration 1
and 2 systems is the Asynchronous Communications Interface.
All software beyond the ROM Basic (by MICROSOFT) is extra
cost. Asynchronous communications software is $40, Pascal
is $300 (requires two floppies and big memory, I think),
Adventure is $30 ... more details when I have the blue
letter in my hand. The minimal systems (system unit, 16K
RAM) will only be available from Sears and Computerland.
Volume discounts are available ... 5% for more than 20
units on up to 15 or 20% for >100 units.
The processor is an Intel 8088, which is the 8 bit bus version
of the 8086 ... it is a 16 bit machine shouting through a small
hole. The processor cycles at almost 5MHz. Assuming three
byte instruction and one data fetch or store per instruction,
there will be five memory transactions per instruction ... if
memory cycles at system clock speed (I think that this is so)
then they get about 1 microsecond per 8086 instruction. The
first 64K of RAM plug into sockets on the main processor board
... you don't have to buy the RAMs from IBM ... you can get
the chips from a distributor and save bucks.
Almost all of the software (read ALL) is from outside. The
floppies and the printer are also OEM components that IBM
buys. The monochrome display is capable of displaying 25
lines of 80 characters ... the TV interface is limited to
25 lines of 40. The monochrome display may have monochrome
graphics ... the announcement is quite vague.
I priced out the nicest combination of goodies that would
go together in the box ... two floppies, 192K RAM, printer,
display, communications, and it came to about $6K sans
software.
Please let me know if you want more details.

From the 26 Aug 81 issue of MIS Week newspaper:
W.U. TO ACQUIRE 50% OF AIRFONE
Upper Saddle River, N.J.
- Western Union Corp. said last week it has agreed to acquire
a 50 percent interest in a new communications system, owned by
Airfone Inc., that will allow passengers on commercial airlines
to place a telephone call while in flight.
According to Western Union, Airfone has received a developmental
license from the Federal Communications Commission (FCC) to
provide a nationwide, fully automatic air-to-ground radio
telephone communications service.
Initially, Western Union said, service will be provided through
air-to-ground telephones installed in wide-bodied aircraft, which
in turn will be linked with multiple ground stations providing
coast-to-coast coverage. It said a passenger would be able to
place a call by using portable telephones located in various
sections of the aircraft.
The system, it said, is expected to be operational during the
second half of next year.

Wonder if I'll be able to use my TI745 with this service...or

From: Rubin at SRI-KL
Subject: IBM PC, last round
A last note on the IBM PC, and then maybe we can get back to
discussing REAL research workstations (which the IBM PC probably
isn't quite).
I got the literature pack IBM sends out, and would like to correct
something Marc said in his recent note. This literature mentions
only two video interfaces -- one for the IBM monochrome display and
one for a color graphics display. The monochrome board includes a
printer interface. If you get the color board, you buy a separate
printer interface. The color board has 16K RAM for color storage,
used like this:
Text mode -- 16 foreground colors, 8 background
Graphics mode -- 4 colors 320 x 200 (might there be a lookup
table ???), 2 colors (B&W) 640 x 200
The graphics board puts out RGB and composite video. IBM does
not (yet) sell a color graphics monitor or RF modulator, but if
you buy somebody else's, the graphics board will accommodate it.
If you're seriously interested in this PC, be wary of a couple
things: First, the five slots probably isn't enough if you want
> 128 K of memory and color graphics; with luck they'll add a
bus extender. Also, I'm wondering whether any of the announced
software really supports more than 64K in any useful way, or how
soon it will. (Given the slowness of diskettes, you'll need the
extra RAM for decent response time, if the software will only use
it properly). Third, I don't believe the IBM DOS applications
can send their output to the ASCII port; if true, you'd have to
buy their printer (and that's a loss because the printer doesn't
do graphics, or at least IBM doesn't claim it does).
Still, I think this PC has more pluses than minuses, compared
to Apples, TRS-80s, Xerox 820s, ad triviatum. Good hardware,
lots of software, lots of future enhancement, and lots of
support (maintenance contracts, even!). Look for IBM to add
a 5.25" Winchester and lots of color graphics software.
Now, about REAL workstations. I just read a rumor that about a
year from now DEC will be announcing a floppy-based, VLSI VAX
packaged as a workstation. Price about $ 15,000. Supposedly
it's already in beta test. Does anyone know more about this?

Sender: GEOFF at SRI-CSL
Reply-To: Geoff at SRI-CSL
Unless you like getting 3 and 4 digit phone bills, I don't
think you'll want to use your terminal on AIRPHONE. Such
a service currently exists on some United DC-10's using
equipment sold by SKYTEL (or SKYPHONE) using the currently
allocated FCC Air-to-Ground Mobile channels. Last I heard
the charge for use was $15/first three mins (air-time), and
$3/ea. addtl min (air-time). This charge was IN ADDITION
to the Operator Assisted dialed call rate from the ground
base station you were going thru to the person you were
calling.
I have found the mobile phone I havE in my car indispensable,
and havE often wished for similar service on air plane
flights. I just hope thatthe license the FCC gave AIRPHONE
for its developmental system means it will operate on some
new frequEncy allocations, and hence, will be a 'new type
of service' and not subjected to the (excessive) rates on
the current system in use today.
P.S. Wouldn't this have been more appropriate for HUMAN-NETS?
[ It was addressed to HUMAN-NETS as well as to WorkS. It
was deemed appropriate for WorkS because of this list's
earlier speculations on using terminals while traveling.
I Would like to take this opportunity to remind everyone
that almost all of the WorkS subscribers also subscribe to
HUMAN-NETS. The moderators will point out other discussion
lists to submitters when that seems appropriate. However,
the final decision of where to distribute something remains
with the submitter. -- RDD ]

Subject: Works Book
One of the issues that has weaved in and out of the discussion
here is why certain small machines are *not* workstations.
It would seem interesting for the definitive (for this year)
workstation book to discuss this issue, as well, and perhaps
to indicate just what would need to be done to the more common
small machines for them to qualify as workstations. I'm cc'ing
the list on this because I want to hear the flames about how
an Apple can NEVER become a REAL workstation, before I give
specifics!

Here's your chance to "shape" the future course of mouse-kind.
I would like to know what people think the ideal mouse should
be shaped like. Also, should there be less than three buttons?
Note that this is an optical design (the mouse slides on a
surface, rather than rolling) so comments about the mechanics
are not applicable.
Comments will be accumulated on MIT-MC in SK;MOUSE SURVEY
(no password needed to ftp).
Some comments I received so far follow. If you have any
opinions on these, please voice them. Some of the following
comments are mutually exclusive.
------------------------------
The Xerox mouse is too small. It doesn't fit the hand well/it
is hard to find.
The Xerox mouse is too large.
The ISI/TYMSHARE mouse is way too large.
Long buttons are great for accomodating various size hands.
The buttons should have good "bounce" to them to facilitate
double and triple clicking.
The MIT mouse (tan case) seems to be about the right size.
The mouse should have rectangular shape and edges. Any hand
contouring is doomed to failure because of the wide variety
of hand sizes.
The mouse should be rounded to fit the contours of the hand
(prolate hemi-spheroid). The hand should slip naturally into
a "home" position where the fingers rest on the buttons.
The mouse should not be "handed". This is to accomodate
lefties as well as two handed mouse applications.
The wrist must be able to rest on the table with the fingers
comfortably on the buttons. This is necessary for accurate
positioning.
There shouldn't be more than three buttons on the mouse
because two fingers are needed to move it around. Also,
coordination is difficult.

[ If you want a copy of the survey messages and cannot obtain
it yourself, please send a message to WorkS-REQUEST at MIT-AI.
We will be happy to insure pα0λat you receive a copy now. A
file containing all of the responses will be made available
for FTP distribution when the query is over.

SubjEct: Workstations - MicroDaSys 68000
There is a company in California called MicroDaSys, which claimed
in the lAtest issue of EDN to be selling a 68000 Unix system that
looks too good (and cheap) to be true. Two 12mhz 68000s (one for
virtual memory management, with demand paging), and a 6809 for
interrupt-driven I/O. Comes with 6 RS232 ports, running at up to
500k baud, and 4 parallel ports, with handshaking.
A multiuser system comes with 512k bytes of RAM in a 16M-byte
virtual space, 40M bytes of Winchester storage, and V7 Unix.
All for less than $20K.
Does anyone have any experience with these folks? Are they
delivering?

Subject: when are 32-bits coming
CC: dreifu at wharton-10
I assume that the MC68000 doesn't count as a 32-bit machine. Intel
has yet to ship any 432s, so it will be a while before any appear in
personal computers. A VAX takes 400 kbits or more of microcode, and
at least 500k transistors total to make even the slowest one. Even a
chip-set must be fairly complex.
The obvious thing that 32 bits gives you is a larger virtual address
space. Lots of applications are hard up against existing limits, and
must resort to memory management by hand, which is a royal pain. In
addition, 32-bit processors usually have a more complex instruction
set, addressing modes, etc, which allow them to perform better on a
wide range of tasks (ignoring the RISC arguments). Examples are
string and floating-point datatypes. The 432 includes a significant
amount of OS support, as well as provide a capability architecture.
Given the thickness of the architecture manuals, I don't know how well
this will go over.
32-bit processors usually also have a larger physcial address space.
Since 16 Mbytes and more memory will appear on personal computers in
this decade, this is an important consideration.

Subject: #19 and 32 bits
The most important thing 32 bits buys is larger address space.
It was annoying to have to pass around 16 bit pseudo-pointers
on the IBM 1130 (back in '69) to address a data base larger
than 64KB and it is still annoying to have to call the
subroutine library in order to reference an item of data.
Think of 32 bits as more object names one can use in
programming.

cc: schiffman atSRI-KL
To figure out how much an advantage a 32-bit micro would be, first
figure out what a "32-bit" micro is --
There are several things in a computer which have a `size':
1) The width of the accumulators/general-registers
(This is confusing in machines which allow concatenation
of registers like the Z8000). Wide registers gets you
shorter (faster) programs by eliminating extra `name'
references for OPERANDS WHICH REQUIRE THAT PRECISION.
Not surprisingly, 128-bit registers aren't very handy for
programs which only do byte-boffing. In fact, wide
registers HURT for programs which don't need the precision
if having narrower registers means having more of them.
The Z8000 tries to have its cake and eat it too.
2) The width of significant data paths such as the ALU.
(How many bits can you add in one microcycle?
Many machines have a N-bit ALU and an 2N-bit shifter.)
Wide data-paths make atomic operations faster for
operations which require the precision. All else being
equal, however, the wider the data path gets, the slower it
cycles (carry propagation).
3) The width of the processor/memory data interconnect.
(How many bits can you fetch in one bus cycle?)
Wide data interconnects to memory speed up operand
fetches/writes which again, helps only on operands which
need the precision. Luckily, if the instruction execution
unit is at all clever, wide memory almost ALWAYS speeds up
instruction fetches; this can be VERY significant.
Unfortunately, for small systems, cost can be almost
linearly proportional to memory bus width.
Under these criteria....

The table is straightforward, except for the 432. My understanding is
that the 432 has no "general-registers", really. It does have many
internal registers available at the microprogram level, at least some
of which have to be 80 bits to hold results in Intel (IEEE draft)
floating point `double-extended' format. As for the bus interface,
this is rather complicated -- the 432's Bus Interface Unit can connect
to user-designed memory systems of various types. I believe that the
Intel evaluation boards use a 16-bit memory bus. So what about the
432 is 32-ish? Only the obvious, I think.
As for its applicability in personal workstations, I think this is
pretty dubious for the next few years.
* A system including the 432 would be VERY expensive by
workstation standards, even if Intel gave the chips away
(which doesn't seem to be in their plans -- the set
currently costs on the order of a kilobuck). Besides
being very memory hungry, a realistic system requires an I/O
processing symbiont higher in complexity than most current
micro-computer systems.
* A personal workstation system based on a 432 could very
well be much SLOWER than a system based on (say) the 8086!
Sorry folks, a full context switch on every subroutine call
and a domain-check for every external reference is very
expensive. Now if you had, say, four CPU sets in your
workstation, you might very well win -- that is if all your
compute-bound programs divided into four balanced processes.
Intel seems to be saying that the 432 is intended for high-performance
shared-database transaction processing systems. I say that if it's
good for anything at all, its probably just that.

Today's Topics:
Other Considerations Of 32 Bit Processors
Videodisks As Memory
----------------------------------------------------------------------
Date: 21 Oct 1981 1918-PDT
From: SCHIFFMAN at SRI-KL
Subject: Addition to processor taxonomy
In my consideration of the "32-bitness" of CPUs, I now realize that I
left out two other things that have a width:
4) The number of physical address bits presented to the
memory bus.
Obviously physical address bits cost more IC pins and
backplane wires, contributing to cost. Not so obviously,
address bits can contribute greatly to the cost of memory
management hardware (and the time cost of using it). The
point is that you don't really want to pay much more for
physical address bits than you need to address the memory
your systems will be able to afford.
5) The internal "name-space" of the architecture, i.e. log2 of
the number of unique objects that can be referenced.
The reason why we can't more simply define this
(as say, the number of bits in a `pointer') is that
some architectures can have arbitrarily complex ways
of encoding internal names, say by using the data-type
field of an op-code to provide extra "logical-address
bits".
Again, a large name space can be a mixed blessing. One of
the most important (for instruction encoding efficiency)
areas of CPU architecture is how to compress memory
requirements for expressing local names. This can be done
badly for machines with even a relatively small name space
(i.e. the PDP-11, where all offsets take 16 bits).
Under these additional criteria, the updated table...

I reread the 43203 data sheet and decided that the memory data bus
was, by the definition that I gave, not "user-supplied", but 16 bits.
The reason for this confusion is that the data bus operates in burst
mode (only one address output for the transaction) for operations on
words longer than 16 bits; this is real optimization since addresses
usually take as much as half a bus cycle.

Today's Topics: Alto Snipe ReviSited
Symbolics' Personal Workstation Query
----------------------------------------------------------------------
Date: 24 Oct 1981 0057-PDT
From: Chris Ryland <RYLAND at SRI-KL>
Subject: apparently random Alto snipe
To: Editor-People at SU-SCORE
I just sent an apparently snide message to Editor-People about the
Altos and their outdatedness; I realized that this might sound
off-hand or snooty, so let me clarify what I meant, and possibly start
a set of flames.
The Alto, without a doubt, was an interesting toy which gave many
bright people a teething device for their ideas about human
engineering, etc. However, I have a heretical theory that the Alto
did more to *slow down* Xerox in their mad rush for the information
systems of the future than it did to help them. Why? Because it's
far too small of a system to be anything more than a toy, in the sense
of providing enough power to support a very good programming
environment.
For example, because the Alto was so successful as a woristation
within Xerox for the pasT few years, everyone was saddled with them;
this included even the SDD folks, who were chartered to pull together
the PARC tinkerings into some sort of reality (the Star and its
satellites). To build Even a medium-sized system in Mesa would
require hours and hours of sitting at an Alto (well, doing other
things), andthus, forthings like BravoX (SDD folks out there, please
correct me if I'm wrong), building new systems would take far longer
than if some sort of time-sharing system had been around to do the
crunching needed. Only recently did the SDD folks get Dolphins, and
even these were no huge step forward. The Dorado is confined mostly
to PARC and certainly iq too expensive and flakey to replace all the
Altos within the Xerox companies.
In my opinion, the only workstation worth even considering at this
point is the Lisp Machine, as purveyed by Symbolics and LMI. Even the
Current generation beasts are rather underpowered for what they're
trying to do; this is supposedly being solved by the next generation
of machines (the only one in the works, as far as the public knows, is
the Symbolics 3600).
Why do I make this extravagant claim, given all the incredibly
wonderful workstations around, such as the Apollo, the PERQ, the
Wicat, the SUN? The reason is software (isn't it always), even
ignoring the pitiful hardware being touted these days as the latest,
greatest thing since sliced bread. The Liqp Machine comes with dozens
of man years of software investment, and those are years invested in
whatis by far the most synergistic environment you could hope fOr,
given the state of technology. I would make the cLaim that nothing
elsa cOmas Within 5% of matching that environment, though I have no
way of proving that claim. A good indicator might be a simple
aneCdote about IJCAI '81: when the Three Rivers folks actuallq sat
down with a Lisp Machine (in anearby booth), they were astounded(I
shouldn't put feelings in their hearts, And this was reported by a
Lisp Machine type, but I can certainly understand any astonishment,
having seen the PERQs and having worked with Lisp Machines!)
Admittedly, other people have gone long ways towards building
excellent environments (the Cedar project at PARC, and the LRG people
at PARC with their various Smalltalk systems); however, it'll be
years, if ever, before the world gets the benefit of the first, and
Smalltalk is a fairly impressive system, but still has some questions
about viability in "the real world" (for example, Smalltalk 80/81/82
still lacks multiple inheritance).
I guess what triggered this whole flame was the sight of the pitiful
systems being proposed by the real world as useful working
environments. The Xerox, IBM, HP and DEC new "personal systems" are
abject horrors (CP/M, my foot). PERQs are just beginning to get
simple operating systems with real file system support. Every 68000
incarnation in the world has its Unix lookalike, or a XENIX hovering
in the wings. I make the bold claim that NONE OF THEM has anything
interesting to offer other than, perhaps, a large screen.
End of flame.

From: Chris Ryland <RYLAND at SRI-KL>
Subject: Symbolics; Alto snipe
Symbolics does manufacture a personal workstation; see my previous
WorkS message about the Lisp Machine. They will support Ethernet
hardware on the next version of their machine (the 3600), but it will
speak Chaosnet protocols softwarily (of course, I shouldn't prejudge
their longer-range plans about protocols; one can assume they'll
attempt to live compatibly with other Ethernet protocols via suitable
encapsulation on the 10Mhz ether). Call them in LA if you want more
info. (No, I don't get any commissions from them.)
Let me clear Up my previous "Alto snipe" lest I appear completely
insane. I stated my position about the Alto somewhat provocatively,
but I didn't mean to imply thatXerox has made some huge mistake in
using the Altos extensively in-house; they never had much alternative
(I also wasn't pushing for time-sharing systems, but rather advocating
powerful servers for when you need to crunch). What I meant, rather,
was that the outside world has always been dazzled by the Altos, which
are, when you get down to it, rather "cute". However, their "punch"
is fairly minimal, and they have always lacked the kind of
comprehensive environment which makes a system such as the Lisp
Machine so attractive. For example, although various Smalltalks on
various Xerox machines (not copiers; Altos, Dolphins, Dorados) do
provide a fairly comprehensive computing environment, they've never
had an editor or a mail system in common use built-into the Smalltalk
environment. I.e., Altos and Dorados tend to be used as tiny
single-user "timesharing" systems, in which you have the usual
executive/program dichotomy. (I used Altos enough at MIT to learn to
dislike them, though they're wonderful intelligent terminals.)
On the other hand, the Lisp Machine provides a completely homogenous,
"vertically integrated" environment, in which the editor, mail system,
compiler, network file server (yes, each machine has a file server),
network file user, local file system, interpreter, window system,
etc., are completely useable at any level by any user (Lisp!) program.
The folks who built these machines at MIT (now dispersed to various
companies) spent a lot of time making the system software
comprehensive and useable.
For example, someone here wrote an Alto Draw equivalent (roughly the
same functionality, without all the bells and whistles) on the Lisp
Machine in a week of spare time hacking (mostly spent learning the
window system); in otherwords, there is a vast range of functionality
available through the system software, which is fairly easily extended
via Flavors.
This is not to say these machines are without problems. For example,
the system, as you boot it up, occupies about 5 megabytes of virtual
memory. That's fine, but clearly, you need a good deal of real memory
to make things work reasonably (1.5-2 megabytes seems to be
comfortable). And, these machines are NOT fast; no one has been able
to compare them to other machines to anyone else's satisfaction, but
there's a general feeling that they're faster than a KA-10 and 2-3
times slower than a KL-10. They don't do arithmetic very rapidly (an
integer add seems to take more than 10 usecs, for example), but this
isn't a fair yardstick for their basic speed. A lot of speedup is
promised for the Symbolics 3600, esp. in the area of function calling
and message passing.
Perhaps I can best summarize this flaming with a suspicion which only
time will bear out: to provide the kind of comprehensive computing
environment which the Lisp Machines are approaching, you're going to
need a heck of a lot of hardware power (virtual memory, microcode
space, raw microengine speed, paging disk speed, etc). And I don't
think any of the other current offerings come close. I don't mean to
say that you can thus write off all the workstations on the market,
but that you can't expect them to provide anything else than a
bare-bones world, or a fairly tightly-bundled, special-purpose
environment (such as the Star). That's sad, because the "real world"
seems to be making all the mistakes of yesteryear all over again (it
happened with micros and it'll happen many times more), instead of
starting with the best that we've got and building from there.
(I forgot to mention the Dolphins: they seem to be fairly good
Interlisp engines: Xerox EOS claims they'll be KL-10 speeds or better
after some software tuning. However, their major problem, for an
experimental environment, seems to be their lack of common bus
connectability.)
(Oh yes, though this is getting long-winded, I can't shouldn't slight
Xerox: they HAVE built a very good software development environment
for Mesa on the Dolphins and Dorados. But I don't think this'll see
the light of day for a while, if ever. And, Mesa is a compiled
language lacking more modern message-passing concepts (though I did
hear that the Star software was built with a Flavor-like package built
on Mesa), so you don't get the kind of dynamicity you would with Lisp
or Smalltalk.)

Re: MC68000 paging
Someone who works for a company that produces specialized computer
systems has been telling me that they decided to build their next
system around the Z8000 rather than the MC68000 because they had
serious doubts about being able to do paging on the MC68000. They
claim that there iq a design problem that prevents instruction
resumption after a page fault. I understand that Apollo solves the
problem by using 2 68000 chips.
Having briefly studied the instruction set and architecture of the two
CPU's, I see the MC68000 as supeRior for the application od this
company (they want a large virtual address space that can be accessed
from a high level language, and speed is important), and it seems to
me that gettingstuck with the funny segment Addressing of the Z8000
will cause problems.
1) Is there a real problem implementing virtual demand paging on the
MC68000?

2) Can anyone tell me some of the problems one faces when generating
code from a compiler (e.g. C) for a segmented memory machine such
as the Z8000? I know that you have to do array subscripting
carefully, but what are some of the more insidious subtle problems
that come up?

From: Daniel L. Weinreb <dlw at MIT-AI>
Subject: Languages and Lisp Machines
Eric Cooper is correct: Symbolics will support Pascal, Fortran 77, and
C on the 3600. This may work by actual translation into Lisp, or by
translation into an intermediate representation inside the compiler.

From: Hank Walker at CMU-10A
Subject: autoinc/dec
It isn't that hard to implement autoinc/dec. The 11/780 has an RLOG
stack containing 9 locations of 5 bits each (I think). Whenever you
do an autoinc or dec, you push the inc or dec value on the stack. On
a fault (any kind of fault), the microcode pops the stack values and
reverses the operations. I can think of lots hairy problems with
backing out of instructions than this.

Subject: Re: Demand paging on iAPX 432
To: Schiffman at SRI-KL
cc: FRANKEL
The intel iAPX 432 does not support any form of demand paging, but,
rather, has a fairly primitive segmentation scheme. This scheme
allows segments to either be entirely swapped in or not in memory at
all. The dual 68000 implementation allows for true demand paging with
the restrictions already enumerated. Other 68000 solutions include
restricting the instructions that a compiler will generate so that the
page fault address can be detected and the code resumed (using only
one 68000). Motorola is in the process of coming out with a new 68000
that corrects the "bus error" problem and some really minor
annoyances.

In response to Peter Deutsch's mail, I should once more emphasize that
my initial flame was mostly in reaction to the world's tendency to
adulate the Alto; as Peter pointed out, the folks at XEROX knew long
ago that they had outgrown the machine, but I don't think that's clear
to the world at large. I didn't intend to slight XEROX. And, yes,
the Dorado certainly "whup[s his] ass" off the current Lisp Machine,
though it's a little hard to determine the relative speeds, given the
different word sizes and internal data path sizes.
Now, my query, addressed to those of you who are contemplating using
personal machines for high-end, mostly stand-alone cOmputational
αneeds, i.e., AI (speech, robotics, vision), VLSI design, physics,
etc.: what is your Sense about the language base you'll need for your
work? This begins tk approach "theological" issues, but I still think
it's an interesting topic.
FOp example, my Feeling (shared by some, I hope) is thatthe only Two

probably be 1 year at least before it is solidly up on an acceptable
machine, such as the Dolphin, Lisp Machine, or what-have-you hardware.
Can you wait for something which isn't a sure bet yet?
Yet, Smalltalk also appears to have a good chance to be widely
available on eveRy imaginable size of machine, which can only bode
well for the availability of good software, people versed in the
language, transport- ability of research software into the "real
world" (and vice-versa), etc. For example, it is confirmedly rumored
that DEC is basing their personal VAX's system software (the SUVAX) on
Smalltalk, and this system has a rather good graphics interface. Of
course, HP, Tektronix, Apple, and DEC have been working with the
pre-release of Smalltalk for nearly a year now, so that provides
further reason to believe that it will have acceptance in the
industry.
Enough speculation. Comments?

Subject: Re: Demand paging on iAPX 432
To: FRANKEL at HARV-10

The Intel iAPX 432 does not support any form of demand
paging, but, rather, has a fairly primitive segmentation
scheme. This scheme allows segments to either be entirely
swapped in or not in memory at all.
``Primitive segmentation''??
When you think about it, pages are only fixed-size segments that must
"either be entirely in memory, or not at all". Segmentation is
clearly a more "sophisticated" quantum of memory management because
objects don't come in fixedsizes. Unfortunately for computer
architecture, it is difficult to ALLOCATE memory if you don't pretend
they do.
¬
The 432, which can have umpteen thousand segments defined ata time,
(with each one being a typed protecTion domain) is considerably more
sophisticated when iT comes to virtual memory management than any
other microprocessop will be fkr a LONG time. In fact, it is more
Sophisticated than [almgst] ANY existingcomputer's memory management
architecture.
Of course, the implementation is such thatonly a few segment

the 432, one would find that there are not enough segments to allow
each dotted pair or even each list to be a separate segment.
In many respects there are a large number of existing computers with
at least as sophisticated an MMU.
The 432 is certainly a large accomplishment for microprocessors and
(except for its poor performance) should find good acceptance in the
Pascal/Ada market.

Subject: Programming languages
I agree that Smalltalk's uniform use of message passing for all
operations is more simple and elegant than the Lisp Machine's mixed
use of simple (non-generic) function calls and (generic) message
passing. However, I think that it would be very hard (though maybe
not impossible) to use message passing everywhere without sacrificing
a great deal of speed. In practice, it does not seem to hurt is much;
the language has function calls and it has message sends, and both do
argument-passing the same way; the only difference is that in one case
you name a function directly, and in the other you specify an object
and a message name, and the flavor system finds the function (the
"method") for you. We use function calling for simple things, and
full message passing when the modularity is interesting enough to
require the added flexibility and control that message passing gives
you.

space, which was itself paged. This gets complicated, though, and one
must draw the line somewhere.
It would be possible, for instance, to implement an APX-432 paging
system which used a dual processor approach to give the "problem"
processor the appearance of as much actual physical memory as the chip
can address, and use a "supervisor" processor (not necessarily a 432)
to read in pages from disk when they are found to be missing. This
would let the 432 programmer use segments with wild and gay abandon,
never explicitly reading them in.

Paging ↑= Segmentation
Segmentation is address space management technique, though it is often
treated as a second level of paging.
Paging is a memory management technique used by the system, though
some systems are not careful about layering and let it show through to
the users.
Guess we need new words to avoid confusion not only due to word
inflation but architectures like the IBM /38 and probably the iAPX 432
which do not make sharp distinctions.

Your message announcing the availability of the Alto User's Handbook
received rather wide distribution (for example, I believe it appeared
in the WorkS digest). I would appreciate it if you would convey the
following clarification to Editor-people and any other lists you know
about to which your original message was distributed.
While the Alto User's Handbook has indeed been clEared for
distribution oUtside Xerox, it has not been brought out as a PARC
external repopt. Our present supply of Handbooks is limiTed, And we
do not have the resources to satisfy the lArge demand that would be
generated by A public release.
Our Past practice has been to sell Handbooks, at Cost, to
organizatiOns that have Altks (principally atCIU, MIT, Stanford, and
UnivEpsity kf Rochester). But eveN thiS is Ending, since we are no
longer actively deveLoping or maiftaining Alto software at PARC;
consequently, we are unlikely tk reprint the Handbook again.
¬
People who do not have Altos may be interested in more general
technical reports on the Alto and Alto-based software, available in
the open literature. The most comprehensive report on the
architecture of the Alto itself is "Alto: a personal computer", which
appears in the recently-published second edition of "Computer
Structures: Principles and Examples", edited by Siewiorek, Bell, and
Newell (McGraw-Hill). Additional good sources of papers relating to
the Alto and follow-on machines include the last two years' SOSP
proceedings and several issues of CACM.
Wa have published a number of PARC external reports on Alto-based
systems. These are available on request, though again we are unable
to satisfy an enormous demand. Many univerqity and company libraries
subscribe to the PARC report series, so you may be able to find coPies
in your library.

How will one program workstations? Will it be easier? Will there
be other proceedures than those of large systems or simply a

The excellent August (July?) issue of \Byte\ was dedicated to Smalltalk,
written completely by members of the Smalltalk development group. This
is the best source of information about Smalltalk until the two books
come out.
If I remember correctly from that issue, the old Smalltalk virtual
memory system (called OOZE) allowed as many as 64K objects, but that
limit was reached, so the new system allows more than 64K objects.
This means that the Intel iAPX [what do those letters stand for?] 432,
which allows no more than 64K objects, would make a bad Smalltalk
engine.

Programming Personal Workstations
Smalltalk, Paging/mmu on the 432
----------------------------------------------------------------------
From: Chris Ryland <RYLAND at SRI-KL>
Re: Smalltalk info
Peter Deutsch is probably the best person to reply to the query about
Smalltalk, but here's something: Smalltalk-80, the only Smalltalk to
make it out of Xerox, will be available sometime around the end of the
year. Adele Goldberg's group, (formerly?) called the Learning
Research Group, is going to publish "the book", which will tell you
all about the language, styles of use, etc., as well as the
nitty-gritty of what it takes to bring up the system (via a virtual
machine) on your favorite hardware; and, they'll license "the tape" to
organizations, said tape containing the "vIrtual image" and all the
system sources. With that tape, and the book, you can bring up
Smalltalk in its full glory by merely implementing the virtual
machine.
The big question at this point is how the tape licensing goes.
There'll be no problem or real expense for universities, of course,
but commercial firms will have to negotatiate with Xerox lawyers
according to their intended use of Smalltalk (e.g., for internal use
only, or for resale).
Adele may want to say something over this medium to clear up any
confusions, but, then again, we might as well wait the couple of
months it still seems to be before the book is published and the
licensing arrangements announced.
(There are said to be pirate copies of the book floating around, but
they're useless at this point, in any case, as they're rather out of
date. This is by hearsay.)

"Reduced scale" my eye! Over a thousand man-months and a
quarter-million lines of Mesa have gone into Star, with roughly thirty
programmers going at it for roughly three years. And that doesn't
include the underlying Pilot/ Mesa/ Communications stuff, which would
add another 50 to 100 %. I don't know how that compares with OS/ 360,
but it certainly qualifies as a large system. And one can imagine all
sorts of applications built on top of Star or similar workstations
(data base, information retrieval, realtime data acquisition and
analysis, ...) that would be of a similar scale. In fact, almost any
application more sophisticated than running the payroll is probably
amenable to a distributed implementation.

Subject: Smalltalk on the 432
cc: kendall at HARV-10
Actually, the iAPX 432 would make a very good Smalltalk engine. It
supports 16M segments, not 64K, so object address space is not a
problem (64K is the size limit for any one segment -- probably not a
problem for Smalltalk, but a big limitation otherwise). The 432's big
win for Smalltalk would undoubtedly be its fancy context switching
(with dynamic memory allocation, even!) and hardware support of typed
domains. Since domain objects can be linked into complexes, the 432
also lets you realize the Smalltalk concepts of classes and instances
almost at the hardware level.
People seem to think the 432 will be really slow, but I'd be
interested to know if Intel has got any benchmarks yet. Based on
their initial literature, the 432 looks about as fast as a mid-range
mini for typical stuff, but it is faster than probably anythingelse
if you lOok at its operatingsystem primitives (e.g., send message is
00 microsecs, and their send primitive is fancy). Of course, the
question is whether Those primitives are useful as they stand, or
whether you need to crust a lot of software around them to get a
decent Kernel. If not, response time and throughput at the
application leveL should be quite high (eXcept for number crunching)
because of the incredibly low OS overhead.
By the way, my guess for the iAPX acronomym is: i -- Intel, A --
Advanced, P -- Processor, X -- makes it sound scientific (or maybe the
X stands for *, in other words, multiprocessing).

1) As for the 432 segmentation setup being too small, that is what
Prime uses for their segments, and it works just fine. As for
arrays that are larger than 64k, lifes tough all over, isn't it?
2) The nastiest page fault problems come not from auto{inc,dec}rement
stuff, but from instructions which modify memory/registers in a non
un-doable way...That is, the AND/OR type instructions....Apparently
(I am told) on the 68000 it IS possible (using the 2 chip) scheme
AND limiting the instrucitons generated by the compilers (and
assemblers, for good measure). This scheme is used in the Micro Da
Sys 68000 system andworks fine...

To: StavRos M. Macrakis <MACRAK at MIT-MC>
cc: TonyWest at PARC-MAXC
About finding out more technical information on the IBM System 38:
There was a nice collection of technical papers published by IBM in
1978. You might try to get hold of it:
"IBM System/38 Technical Developments" published by IBM GSD (then)
publication order number G580-0237
However - I think this report is out of print, in which case, what I
recommend is that you call an IBM branch office, tell them about this
report and what you want, and ask them to look up for you the list of
publications available for the S/38 (which has since been announced,
so there is plenty available about it). All Branch offices have a
list of publications and can order them for you (though you may have
to produce some money sometime for the books).

Subject: Suitable workstation languages?
Being of the Evolutionary, rather than Revolutionary, school of
thought I've been concerned over means for experimenting with a
language like Smalltalk on a UNIX (i.e. READILY portable TODAY) base.
The approach so far has been to use the C compiler as an "assembly
language" for a virtual Smalltalk machine; i.e. to develop a Smalltalk
compiler that produces C language as output, and then bootstrap from
this to versions that bring up more and more of the stuff that UNIX
doesn't help with (automatic garbage collection, incremental
compilation, etc, etc.).
The part that works so far is as follows: a C precompiler (of the
lex/yacc school) reads a language close to C, and turns that into C
language containing data initialization statements that define class
relationships, in a manner as close to Smalltalk as I can glean from
the available information. So with this one can experiment with
programming in objects, classes and messaging, although the input
syntax isn't Smalltalk 81 and most of the Smalltalk 81 environment is
also missing.
The next step isn't working yet, but should be soon, which is to
complete a (non-incremental) compiler for Smalltalk 81 syntax, which
uses primitives generated from the step above for data storage.
This compiler generates interpreted code, for which an interpreter
will be written (in preprocessed C).
Subsequent steps can also be envisioned, but I'll probably stop
this approach well short of "Complete Smalltalk on UNIX".
Any interest out there?

Technology wise we will probably see an S-machine, microcoded to do
the byte-code operations very efficiently.
Will the 'programmers of tomorrow' use this concept in programming
versus classical PASCAL/Fortran/ . . . styles ?

Subject: more on VMS
¬
When VMS was first being written, they had a Goal to fit it into
64Kbytes. Since current versions lock 800-1000 pages to VMS, they
have obviously gone way beyond this. But the size constraint may be
an additional reason to scrimp on the user interface. Someone now
stand up and say that UNIX is small. Yes, but its user interface is
no better, and VMS provides more capabilities.
[There is also a discussion of VMS's user interface in HUMAN-NETS.
I would suggest thatyou address any further discussion on that
particular topic to HUMAN-NETS@AI -JSOL]

From: Mark.Tucker at CMU-10A
Subject: Portable Smalltalk System
Message-Id: <09Nov81 153741 MT71@CMU-10A>
The best way to obtain a portable Smalltalk system would be to code
the Smalltalk virtual machine in some suitable algorithmic language: C
would be fine. Then, get the rest of the environment by importing the
Smalltalk virtual image from PARC. By maintaining compatibility with
the Virtual Machine, all software developed under the portable system
would be valid when the a personal S-machine is eventually perched by
our desks.
Even though Xerox expects the Smalltalk virtual machine to be
microcoded, most implementations will face similiar problems detailing
the way the VM maintains data structures in a byte-aligned memory
space. A well written HLL VM implementation would serve as a
guideline for microcode writers. Perhaps,like Xerox did with BCPL on
the Alto, these HLL procedures could be subsumed into microcode as
time and microstore space would allow.
Finally, I think we want the underlying power of Smalltalk to be
available in some measure on standard 24x80 CRTs. I know this is
blasphemey, but it will be a very long time before you have a bit-map
system at home and at work. So we should start today to consider how
we will have to limit the amount of information contained by a
Smalltalk display so that it will fit in 2K characters. About the
only display format a "portable" Smalltalk system could provide would
be such a restricted, 24x80 one.

Subject: Real World Decisions
It seems that the current discussion, though very interesting, has
gone astray from what we have to consider as today's real problems in
selecting a workstation configuration of modest cost.
At the risk of provoking wild flaming (or utter silence), we would
like to solicit some opinions/advice on the situation we are faced
with right now:
We need to gather some hard experiences with small 4-6 user 8 or
16-bit micros of the Z80 CP/M-based or LSI 11/23/24 varieties,
respectively. These systems are to be used in an environment which
will crudely communicate in a batch fashion to send and receive mail
from a central site. We have plenty of experience with a
multi-processor CP/M system, and we have all of the correspondence of
the recent UNIX vs. CP/M discussion. What we don't have is any
experience with RT-11 that one user is strongly pushing with seemingly
convincing arguments to the novice potential user.
One of his major points is that there is a large amount of free
software available to run on it. There is also a large amount of
software already designed to interface with VT-52-like terminals.
What is not certain is the availability of a decent word processor...
Our concerns are mainly centered around our bias to the
speed/response-time advantage obtained by using a multi-processor over
the small-scale timesharing of something like an LSI 11 running RT-11.
Secondly, we need to know what compiler are available besides FORTRAN
and COBOL. Pascal, C are two others that come to mind.
Now I know that the machines discussed appear to be a step backward in
the high technology discussions carried on here, but we need to know
alot about a cost-effective approach without getting trapped in either
an obsolete technology or a flashy new one which may not get off the
ground.
Please be sure to include ARMTE@OFFICE-8 in your replies.

most current computers are even close to the state-of-the-art, in
programming environments or languages; they use something like OS/360
and COBOL. But workstations are surely at the forefront of
innovation-- the existence of this digest implies it.
And so Xerox is. But although they have had their Altos for ten
years, the only commercial product to come out of that line of
research has been the Star, which is a word processor (a great one, to
be sure) and office filing system, not a full programming workstation.
Perhaps most work- stations will be like the Star, running slick
special-purpose packages, as SSteinberg suggests. But I fear that
Apollo-like stations will be dominant.
My purpose here is not to insult the Apollo. Apollo, Inc. itself
projects that 95% of its sales will be to engineering firms and such
using FORTRAN; this type of customer does not appreciate or want
programming innovations. The Apollo programming environment is very
primitive--indeed, the Apollo system programmers had never seen a
Xerox workstation when they wrote the Apollo software. Note also that
the Apollo is the most sophisticated general-purpose workstation
commer- cially available.
To summarize, I see the possibility for widespread better "programming
of the future", but I fear that the mistakes of the past will continue
to be perpetuated; and I see evidence for this perpetuation.

implementation resides: either the operating system (if any) or the
hardware (if there's nothing corresponding to an operating system).
AcceSs to the bit-mappeddisplay and other I/O devices is likewise
dependent system-dependent, and the parts that don't depend on the
operating system or hardware are probably in Smalltalk code rather
than in the kernel. The second kind of things are those that have to
rqn very quickly, and indeed you might benefit by writing those once
in C and attempting to make the C code portable. I don't know how
much of the kernel makes up the first kind of things and how much the
second kind; perhaps there is a Xerox person around who can comment?

Subject: Smalltalk 80 bible
So just where do I (a humble student) go to get a copy of the
Smalltalk 80 specifications book and the 380K byte system tape?
I read in Infoworld that the Apple IV is 68000 based. I seem
to remember rumours that they had at least the window portion of
Smalltalk 80 up.
The Infoworld article also talked about two other Apple
computers: a redesign of the Apple II for 64K chip, and some sort of
portable (ala Osborne I) 68000 based machine -- possibly code-named
the Mackentosh.
I believe that Tandy is working on a 68000 based machine, too.
In fact, I bet just about everyone is going 16bit because of the
greater speed/power/RAM.

This message was sent to me by a Hardware designer who is currently
working on implementing his own 68000 system. He claims you can do
totally winning paging on the 68000 without kludging two processors
together, by adding hardware to detect page faults, and signalling a
bus error which such an event takes place. If the following is true,
why did people go to such great lengths to implment paging?

Re: 68000 Paging
Howdy!
Ah, but the 68000 has something even better in that it is really
versatile; it has a BERR (bus error) interupt that can either re-run the
bus cycle in case of parity error in memory, or call a routine in the
monitor to modify the page and swap in/out virtual memory. This single
input can (under complete control of the Monitor) trigger any special
routine the user wishes when page faults or other such immediate conditions
occur. Combine this with status outputs that can tell outside hardware
(page-mappers for that matter) whether the currently running program
is Monitor (privileged) or User (ordinary) and you have the basis for a
really sophisticated virtual memory/multi user/multi tasking system with
a minimum of external hardware!

Today's Topics: Demand Paging On A MC68000
Programming Environments
----------------------------------------------------------------------
Date: 24 Nov 1981 10:42 PST
From: TonyWest at PARC-MAXC
Subject: Re: WorkS Digest V1 #39
cc: TonyWest
About demand paging on the 68000 and FEINBERG at CMU-20C's question
about what makes it difficult:
Yes, it is true that the 68000 has a hardware signal (BERR), which
allows external logic to interrupt the processor if any of the bus
cycles in an instruction cannot be completed (eg. because the page is
not there). The hardware to detect references to missing pages and
generate this signal is trivial.
However, that is only half a solution to the demand paging problem.
The other facility that is required is that, when such a fault occurs,
it must be possible to stop what you're doing, load the page, *and
continue again*. There are two approaches one might take:
Scheme A: On a BERR, store the entire state of the processor and
restore it after the missing page has been loaded so that the
execution of the instruction can be resumed from whatever intermediate
point it got to before it faulted (ie. don't restart the instruction
from the beginning -- continue from where you left off).
Scheme B: If one could only figure out which cycle of an instruction
caused a fault, then, with the help of some code (which is rather
similar to an instruction disassembler), one could undo the work the
processor has accomplished so far in the execution of the instruction,
and *then* save the starting state *before* the instruction which
failed. Thus, after loading the page, the instruction can be re-run
from the beginning (ie. don'tcontinue from where you left off --
unwind the partial instruction and try it again from the beginning
later).
The problem with the 68000 that everyone has been talking about is
that, on a Bus Error interrupt, the facilities the 68000 provides for
getting your hands on the internal machine state *within* an
instruction are deficient. Thus it is extremely difficult or even
impossible to "trigger any special routine the user wishes when page
faults or other such immediate conditions occur" and have it unwind
what's going on successfully.
For Scheme A, you can't restore the 68000 to a previously-saved state
halfway through the instruction.
For Scheme B, it is extremely complex to undo the instruction the
processor has half executed so it can be re-run later. One encounters
problems with things like auto-increment addressing modes, etc.
I have seen it suggested that, by carefully restricting the set of
instructions a code-generator is allowed to generate (eg. by avoiding
things like autoincrement addressing modes), a system designer can
reduce the range of possibilities of what might be going on when an
instruction faults to manageable proportions. However, *intimate*
knowledge is required of the way the instruction processing is
performed.
If you have to have demand paging, consider the following suggestions:
a) Implement the two-processor scheme and have done with it. You
sacrifice performance and multiprogramming during page faults.
However, it's makes for a very simple system.
b) Call Motorola and ask them about the timescales for availability of
the following two devices I saw advertised in some of their literature
(I quote verbatim):
MC68010 Virtual Machine
This processor is an extension of the MC68000 that
readily supports advanced virtual memory techniques.
MC68020 Advanced M68000 Processor
This advanced 16-bit microprocessing unit will feature
architectural extensions of the MC68000 such as
virtual memory, co-processor support, string handling,
and higher performance.
c) Consider using the National Semiconductor NS16000 microprocessor,
which will soon be available, and will support demand paged virtual
memory from the beginning. Datasheets are available now from NS. This
machine is in the same architecture and performance class as the
68000.

to the subject.
Software Engineering Environments, ed. Horst Hunke/Huenke is the book
I had in mind. But note that, e.g. Transactions on Software

Re: The M68000 paging question about what fails with the facilities
Re: provided by Motorola.
Demand paging requires more than simply detecting when a non-resident
page has been referenced. Since instructions will be only partially
complete when a page fault occurs, it is generally necessary to bring
in the non-resident page and restart the instruction. To do this
properly the processor must save sufficient state during the bus error
interrupt to backup the instruction iF not to the beginning then at
least to the point where it can proceeD, recalling that servicing the
interrupt will change the processor state. It is known that certain
M68000 instructions, including some very useful ones, do not save
sufficient state to restart these instructions. Since Motorola's
position iq to fix this in some future version, some users use
compilers which do not generate the offending instructions program
with these compilers. Others adopt the two processor solution
described elsewhere in these pages.

In November 1981 MINI-MICRO systems pp199-200 is a description of
a few of the Operating System classes around. In addition there
is mention of iRMX/MMX and iRMX86. The big concept though, is the
possibilities of combining an Opsys with all the new technology.
Though the article is heavily skewed towards Intel, the idea is the
same: What should the Opsys be at the Personal Computer level?
There is some mention of layered Opsys's with actually embedding
parts on the chips themselves.

Am I correct in my assumption that most of the
auto[increment|decrement] modes of the MC 68000 would have to be
avoided to permit demand paging? Is this not like purchasing a sports
car to drive to Church on Sundays? I would find it hard to believe
that satisfactory performance could still be squeezed out of the chip
if it was limited in this way -- I'd certainly like more details on
just what must be avoided (and at what cost). -IAN!

You are not correct in that assumption. A real implementation of this

fact that Multics looks at everything as if it's in memory, and that
"files" are a convenience to the user more than anything else.
What's the real story here? Any such systems around, which really
make use of a large address space in virtual memory? Any workstations
around which do this? Is there good reason for a workstation in
particular to be \able/ to do this or to be engineered to take
advantage of using a very large virtual address space in a really
aggressive way? Or will "good old software" for workstations be okay?
Does it matter for workstations if they really \are/ 20-30 years
behind the times, as someone has suggested most systems are... is it
that much of a pain in the neck to those who design them?

Subject: 68000-based APPLE
Does anyone have any information about the new APPLE system,
supposedly 68000-based? Will it be cheap or expensive? Will it
have a bitmap? Will it truly run Smalltalk? When will it be
released? Etc.
Rumors are welcome.

Subject: SUN Workstation
On about 13-July there was an entry in this digest from Andy
Bechtolsheim (AVB at SU-AI) describing the Stanford University Network
workstation: 68000-based w/ 1Kx800 BitBlt display, mouse, Multibus,
Ethernet interface. I later requested more info from him on the SUN,
but my request went unanswered.
Particularly in light of the discussion in this digest regarding 68000
paging problems, it would be interesting to know what approach they
have taken in designing the SUN. I assume it's not the same "solution"
that Apollo used (twin 68000's), since the 13-July synopsis simply
described the processor as "8 MHz 68000, executing without wait
states". It does, however, offer both segmentation and paging
("two-level, multi-process, segment-page memory map"), so the problem
is there to be solved. Does anyone know how they handle it?

------------------------------
End of WorkS Digest
*******************
-------
The SUN workstation indeed uses a segment-page scheme that
supports a 10 MHz 68000 executing without wait states.
No attempt has been made to simulate full virtual memory with the 68000.
Instead, the SUN has been designed to use the 68010, the virtual memory
version of the 68000 that is expected for 3Q 1982.
The 68010 has the same pin-out as the 68000, but handles
instruction aborts correctly and has a number of other small enhancements
such as an interrupt vector base register and programmable function codes.
The announced report on the SUN workstation is finally available.

APPLE 68000 Rumor Answered & Query - 60010 With Paging
----------------------------------------------------------------------
Date: 4 Jan 1982 04:27:26-PST
From: pratt@Shasta at Sumex-Aim
Subject: Sun paging (and status)
To answer the question about paging on the Sun:
While the Sun does indeed have paging it Iq not demand paging, at
least not with the 68000 processor. The paging unit serves two
purposes: to provide hardware support for memory allocation at 2K
(page) granularity, and as a place holder for the 68010, The promised
VM 68000. The Sun is designed to perform demand paging with the 68010
as currently spec'd by Motkrola.
Given the inability of the 68000 to wori on other things while waiting
for a page in the twin-processor solution, not to mention the
additional complexity of that solution, we decided not to go the
twin-processor route. (This isn't the NIH syndrome, Forest Baskett
was kicking around the twin-processor 68000 idea at Stanford two or
three years ago.) We felt that a more satisfactory approach was to
build a non-demand pager for non-VM applications and shift our
attention to the VM applications when the 68010 appeared.
While VM would be nice right now for our purposes, we are still
managing to develop a lot of our software without it. You can make up
for no VM to a considerable extent by being rather more generous with
memory; Unix runs nicely on a Sun with 768K of memory, the size Sun I
have iN my office at The momant. (That doesn't count the 128K of
graphics memory). However it WOULD make our programming a Lot easier
if we had VM. (MoTorola, take noTice.)

The graphics board is licensed to Forward and CadLinc. The Ethernet

Of the above manufacturers, only CadLinc is presently in a position to
offer a complete packaged Sun. Stanford has been quoted a price of
$6800 from CadLinc for complete Suns (including mouse). However it
would cost Stanford only $4900 + labor to plug in assembled and tested
boards (at prices available to Stanford) and bolt the packaging, power
supply, and card cage together, where labor = 1/2 day at the most, so
we're not inclined to take the $6800 figure as the rock bottom price
for Suns at Stanford.

At Stanford we presently have 10 Suns in operation. Three are
graphics workstations, three more are Ethertips (terminal
concentrators with 16 lines on two of them, 32 lines on a third), one
is a "bridge" (pseudo-Gateway), one a software development station,
one the LOTS workstation, a partially built 16-processor teaching tool

cannot be accessed as primary memory; special access methods must be
used. Back when I was using Multics, many of the systemutilities
didn't understand about such beasts, and hence could Not be used on
multisagment files. But it isn't clear tk me that enough bits could
have been allocated∞ Historically, essentially every machine ever
built (or itq program-compatible successors) has run out of address
space bits; furthermore, such bits are a scarce resource for the
machine architect. To expect a general-purpose CPU to reserve enough
bits to address the large files we can expect to use in the future
just isn't reasonable; the alternative would slow down performance the
rest of the time.

Subject: 68000 Apple rumor response; (unrelated) 68010 with paging query
My sources told me that the Apple IV would have a pair of 68000's --
one to run just the keyboard and bitmap display, the other to do the
"work". It would run smalltalk. I don't know the resolution or the
mouse quality, storage size, interfaces, etc. Presumably it would not
support paging until Motorola fixes the chip.
On that topic, I heard a number recently -- 68010 -- which was
supposed to be the version that supports page faults. Does anyone
have any further info?

There are actually a few related concepts:
Uniform addressing --
This is used by both Multics and the IBM/38 among others.
It means that one can just name an object and need not
worry about how to acccess it, i.e. via memory or via a
file system. This is closely related to object-oriented
architectures, though Multics represents an earlier
approach and deals better with large objects than small
ones.
Large address space:
This means that the set of objects that can be named is
sufficiently large and can be represented in a virtual
memory.
Large memory:
This simply means that one does not have to spend most of
the time developing strategies to fit inside of a small
machine. Of course, when one has a small machine reality
can impinge. A large address space with a small memory
can be inefficient, but this is relative. The concept of
a working set is real and effective.
Memory based communication:
This is important in Multics, but can present problems in
distributed architectures. But is it actually possible to
distribute a memory based system. Message based
communication is simpler to distributed since all one need
do is implement the interfaces and thus can support
communications among heterogeneous components.
These concepts are all relevenet to work stations. Basically,
having a large uniform address space with sufficient physical
resource to support it greatly reduces the cost of
implementation and makes for a more effective implementation.
I think Star attempts to do this, but doesn't have enough
physical memory to make the best use of its architecture -- at
least in the first implementation.

Subject: large address spaces
I know that Multics uses its large address space well. A
workstation designed which uses its large address space is the
LISP machine being sold by Symbolics. My fEeling is that it is
possible to write software for poorly designed hardware running
horrid operating systems but there is no need to do so, It is
possible to waste time with dippy Address spaces and
atavistically designed operating systems but it is a lot easier
to just concentrate on new applications.

While this not a Multics forum..
The comment that the Multics segmentation scheme fails because
it does not handle large files is wrong. This is saying that
it fails because the scheme does not support record files,
indexed files or whatever. In fact, these are all objects that
normally use program mediated access (i.e., an I/O sye fact that Multics streamlines the simple cases and provides
efficient mechamisms for implementing files (i.e. directories
of segments -- the multisegment files) does not meant that it
is bad, just that programmers fall into the trap of using the
nonmediated direct access to segments because it is there, not
because it is appropriate for a particular application.
It is also a FEATURE that segments and offsets are independent.
If increasing the offset did go over into the next segment,
errors in address arithmetic could result in bashing some bits
in some utterly unrelated an innocent object. Since offsets,
not segment numbers, are normally used in program address
calculations bad programs would only clobber the segment they
owned, not another one. This random clobber is particularly
nasty because it can go undiscovered for years -- long after
the cause and knowledge about how to recover has been lost.
This is not to say that Multics is perfect, but much of the bad
press is undeserved.

Subject: questions I'd like to answer
Generally, I find myself bored with the content of WorkS. THus, to
spice it up let me ask some questions that I care about.
1. Rather than worrying about chips I care about the packaging of
those chips into workstations. What are the best 68000 based products
people have seen out now that so many are being announced (Computex,
Dual, Wicat, Charles River Data Systems, BBN's BitCraph...)?
2. Is a multi-processor workstation a good idea (for dynamic graphics,
for example)? Adding additional hardware processors with shared
memory doesn't seem to add much to hardware cost, so why has no one
done it?
¬
3. I hypothesize that sound output on a workstation is cute, but a
terrible product idea (in shared offices, it is annoying...). For
similar reasons sound input is a problem. Is there a good use for
sound in an office?
4. How do you train users of winchester-based systems to do proper
backup so that they don'tlose everything the first time their disk
fails? Is there a technical solution (require a local net with a
backup server?)
5. There seem to be two distinct design points forworkstations
regarding theeir communications environment -- either they are always
connectedto a net And always listening(formail, e.g.), or they are
only connected when the user is runjing a communications appl. (such
as FTP or fetchingmail froma mail drop server). Each is workable,

Subject: What's a WorkStation
Seems to me thatthe definition is a function of the kind of work that
needs to be done. For the moSt part, the recent Discussion centers
around S&E applications programmifg as the wori - and there are those
who will say, won't a relatively dumb teriinal connected to a super
mainframe do the job...
But, there are other kinds of work stations thatare not being
discussed here, and maybe should be.
One iq the manager's work station. He's the one who wants to query
locally shared databases (through a lkcal net) as well as some piece
of much larger databases elsewhere. He also wants to draw
plots/graphs of the expracted data, both on the screen and occassional
hardcopy, maybe attime@LXAS\↓G←Y←HXAM←HABAe∃a←eh↓←dAaIKgK]QCiS←8\@A⊃∀~∃CYM↑AoC9ifAi<AoeSQJAIe¬MhAe∃a←eiLXAaCAKefX↓C]HA

←[akd that memory was
getting cheaper and that virtual memory roached performance and was
obviously unnecessary. Everyone learned to lived in cramped memory
space and thousands of programmer hours were wasted on hairbag overlay
schemes and disk based memory managers.
When minicomputers came out everyone said that memory was getting
cheaper and that virtual memory roached performance and was obviously
unnecessary. Everyone went bananas trying to cram anything into itty
bitty 64K (B or W) address spaces which was especially ludicrous since
the machine often had .5M(B/W) on it.
When midicomputers came out I personally flamed at a couple of the
manufacturers suggesting that they consider putting in VM. They at
least conceded that it could be done efficiently but they couldn't
imagine why I'd need given a full 20 bit address space. When I
explained that I would have to limit the size of the symbol table at
x, they explained that I should write a software paging system.
When microcomputers came out everyone was blown away by the fact that
you could stack 300 of them in the carcass of a bombardier beetle and
have room left over for an I/O multiplexer chip so no one considered
VM. So what do we have today?
"Why can't VisiCalc hold more stuff in it?"
"Damned, the editor buFfer is full again and now I can't
just add memory."
"You can't call a Macsyma program from a PL/I program
because they don't both fit in memory even if there is
enough room."
In other words. Everyone is bumping into the same garbage they bumped
into ten years ago except that more people are bumping into it and
this time we might all win.
As far as segmentation goes I approve completely. Segmentation lets
PL/I call Macsyma since it enforces a set of rules which describe how
all programs have to communicate and it allows them to share an
address space (segmentation is not as important on object oriented
machines since each object can be viewed as a segment).
A very successful segmented machine is the HP41C calculator. It
provides segmentation and dynamic linking in a tangible form. It
provides one system segment, one writable segment and four user
addable segments each of which may contain any number of named entry
points. A key may be bound to any entry point.
When I buy a device, such as the magnetic card reader, I plug it into
one of the segment slots and suddenly I can invoke a whole series of
programs which can read and write data to this device. If I buy the
business package I can suddenly run the TBOND function to evaluate
Treasury bills and so on. I am often surprised that such a simple and
powerful scheme is used so rarely.

to be performance.
The discussion on virtual memory so far has assumed that swap
management is independent of the application. It would appear an
unwarranted assumption. When performance requires it, it is normal to
tweak lower-level virtual machines in one's hierarchy. For instance,
if it is discovered that some particular kind of array calculation is
taking a large fraction of the runtime of an important program, one
may well wish to modify the compiler or the microcode of the machine
one is running on, or for that matter buy a processor which runs that
calculation better. Similarly, it should be possible to define
interfaces to swap management (note, for instance, the ITS paging
parameters PagAhd and PagRange which warn the system of linear sweeps)
which either define a particular regime of swapping or even allow
swapping to be fully controlled by the user process (e.g. in addition
to requesting swap-in oF the faulted page, request several 'related'
pages): A page fault becomes essentially a kind of subrkutine
Invocation.
Demand paging with its various refinements is a sound general-purpose
method, but certainly other methods are possible when the application
warrants.

Subject: page size
While not wishing to extend the infinitely long discussion on
paging, I can't let the references to the VAX page size pass without
comment.
It is true that 8Mbytes is required for the system page table when the
process space is 2Gbytes. However you are confusing implementation
with architecture. Just because the VAX-11/580 has an 8Mbyte memory
limit doesn't mean that VAX-11/XXX will have such a limit. If you
also keep in mind that the architecTure was designed to last a long
time, you wilh realize that 8Mbytes may be only a small percentage of
The physical memory space when 2Gbyte programs becoma cOmmon. This is
not to say that AI typeS hav@∀AShAα+πOE¬∪'∨#"β;?]ph(4*L1βg?*βπK∃π∪↔π3gIβ←?↔∪'↔⊃ε ?W"βS#∃πβπ∨∃π#π 3*βOCπ≤)1β'"β'Mβε{GO'⊗c∀4+&yβπ∪"βπ;?&C↔Iβd+[↔1∧{⊃β'v#'K↔≥#'?9αCπ;⊃ε3π∂S⎇⊃β/→β YβK.#W∂SL{9β'ph+OC∞≠∃%β↔IβCW'#';≥¬##∃β∨KOS↔h∧πε∞|Tπ&∞-HRεNnMrπ& Tπ⊗/<X Nl9λ≤ ≡]λ⊂↔YεE9|\z2v@≤x0qrH1<P6[r4s<Zw3P:~2P0y_t4z2Xz:y2H0z⊂ H3:z:\2P20]2W⊂⊂∩FE27]q:⊂*~0z⊂4]⊂;tv≠⊂2{2\⊂40x≤2w↔⊂λ*44yH4yP9[vr{t_z⊂9t[tv0yλ:7FE∪0z4w[0v∪yH')X[ __⊂9Xt2vrKεEεE⊂P9vp[6⊂80YrP9t↑2P4iH3wwrλ12qp]yrP4]⊂92r≥qryP~w:2y≠0v⊂3≤0svr[:0z4[w↔εE∩z⊂1p[∪z⊂1→P:7wH9vpv≠⊂12qXzyrP~z⊂4yH<wzyλ:w4zλ7s⊂1[vvzw~qpz4[3P;t]4εE:~2P24\uW⊂⊂

the time to 15 minutes. The field service center would call machines
in its area at nieht to perform backup to theiR large disks or tape.
Directories of backed up files would be left behind, or exist on disk
at the center. Ib the user needed a backed up file, the machine would
dial the center, request the file, and have it shipped over the phone
line.
Backup will only succeed if the user has almost no involvement, other
than doing the most trivial of things, such as "insert catridge
MONDAY" or "wait, fetching backup copy...".

Subject: What is a workstation?
Subject: Must works&display and main-cpu share memory?
To: George.Coulouris at CMU-10A
In order for the state as presented on the workststion screen to
be understandable to the human, it must be built upon a small
number of symbols each of which can be learned quickly, the
small number of symbols so that the total system can be learned
in a short time (a small number of quicklies, not a million
quicklies which can be a rather long training period).
That being assumed, it's easy to represent these symbols and
their locations on the screen (x,y offset, x,y scale, angle if
rotated, and which other symbols overlay them). That being the
case, it doesn't take much data to transmit updates to the screen
from the computer that's running the process to the word-processor
that's displaying it. Thus I see no reason to insist that the
whole system (cpu-intensive process, and workstation display)
run in shared mainframe memory. It is sufficient thatay-reasonable network (perhaps 9600 baud).
Thus we design the workstation for editing, display, and network
communication, and leave the cpu-intensive tasks for the big machine
that is shared among seveal users.

Re: Page tables
All this business about gigantic page tables is a red herring. The
Berkeley Computer Corporation machine used a hash table for the page
table. Its size is proportional to the size of REAL memory. In other
words, if you have a 1M word real memory divided into 1K word pages,
the in-core-page table contains a maximum of 1000 occupied entries,
regardless of the size of the address space. The page table is hashed
on the disk address (or unique ID or whatever you like) of the page.
This scheme requires a hardware map that is associative rather than
indexed, but that is no big deal -- it's just like a memory cache.

Subject: 256K bit chips from Bell Labs
The latest Newsweek (Jan 25) says that Bell will release a 256Kb chip
next month. On the other hand, the same story (about Bell Labs) also
says that ACS was secret before the divestitqre agreement....

Subject: arithmetic error: for 84M bits/sec read 8.4M bits/sec
In my last message, the decimal point slipped from my calculation.
However, my argument was based on the correct calculation and
remains unchanged.

Subject: Virtual Memory
As has been pointed out by many folks, VM is a wonderful mechanism for
hiding the actual size of main memory. Programs do tend to be
simpler, and the loss in performance is often quite small, especially
since page fault-initiated I/O is often much faster than ordinary file
I/O. But virtual Memories work well *only* if the program has
suitable locality of referencE, i.e., if the working set is a
reasonably small fraction od the total memory allocated. If the
program is going to access most of its address space without any
particular clumping, performance will badly. Not that explicit I/O
would make it any better -- but at least the programmer would be aware
of what's happening, and would be warned that perhaps a different
αalgorithm might be appropriate. The best example I can think of is
soRting: anyone who tries to sort a large number of records using,
say, shell sort, is in for a rude suprise if the program iS runin a
virtual Memory environment.
Another point: all the world is not in main memory. In particular,
my terminal isn't. One can write Multics-style programs to deal with
files, or one can write UNIX-style programs, in which all the world,
including my terminal, is a file. I don't know which approach is
better.
In short: VM, and memory-based file I/O schemes are not panaceas. I
like both -- in particular I *don't* like systems without VM -- but
there is a tradeoff; perhaps the workstation designer would be well
advised not to spend the extra bits on address space that can't be
efdiciently used by the maximum real memory likely To be available.
(And then add a fEw more bitq because such predictions are always
wrong....)

From: WALKER at CMU-20C
Subject: hard copy
There is certainly no use for an optical character reader to insert a
machine-generated document into another machine, but what about all
the books, papers, etc already laying around? Most of this stuff can
be safely thrown away (look around your office, or at least mine), but
a lot of it is relatively timeless. It would be a royal pain to have
someone type in the Library of Congress by hand.

Re: the whole world is not in main memory (for example my terminal).
Well, It could be, maybe it should be, and on a lot of workstations,
it IS. DMA displays havE all sorts of advatages over any other type
of display. Itq just that if the display bitmap takes 128K bytes,
and your processop only addresseq 6$K, you are in alkt of trouble.

met?
λI wilh list these loose qpecS as my reQuirements fkr a workstation:
(1) Reasonably high resolution and performance graphics, at least 512
x 512 x 1 fop the bottom-oF-the-line system with speed sufficient To
prevent the user from having to wait for screen updates to any
significant degree for most tasks. Higher resolution, along with the
higher speed updates needed to maintain response time, and color, are
options for more expensive models. I assume that the graphics is
raster.
(2) Keyboard and mouse. Voice I/O might be an option.
(3) Access to secondary and tertiary storage.
(4) Processing power sufficient to make my interactive software truly
interactive. I also need power sufficient to handle my large
simulations.
(5) Ability to communicate with other people, again without system
speed getting in the way.
(6) Access to a good printer, although not necessarily Dover-like.
Here are possible ways of meeting the above requirements:
(1) The only reasonable way to meet the graphics requirements is with
a local frame buffer and graphics processor. Communications costs are
too high to do anything else. Most of the cost of this system will be
the terminal and frame buffer, not the graphics processor.
(2) Any old keyboard and mouse will do. The keyboard is clearly slow
enough to be handled remotely if desired. Mouse updates to the screen
will probably have to be handled locally, and don't involve that much
processing anyway.
(3) Disk drives and printers are about the only things that have
economy of scale these days. Given a high-bandwidth network, it may
be possible to eliminate local disk drives, tape drives, floppies,
etc. These are also lower reliability devices, so workstation
reliability could go up. It is not clear whether local or remote
disks will result in better performance/cost/reliability for a large
system, but is a posqibility. A sufficiently large local memory might
cut down traffic enough to avoid a performance penalty if proceqsing
as lkcal, Anyway, there is some possibility that seCondary and
tertiary storace need not be local to a worhπgiCQS←\A%\ABAαcπK∨*βOgO&+58∀T≠3↔π⊗ce!βLqβ¬β≡kπ31ε∪WO'v+GMβ&CπQβ&{↔Mβv{Qβ#∂3∃β∂}sS';.{WMβ∞≠∂πO~↓# ?!Q&∞w∀ ⊗≡≡↑>2JπMtε

From: Jonathan Alaf Solomon <JSOL@MIT-AI>

This is yet another test, to be sure the list works from both AI and MC.
Someone asked me where the archive lives. Here is a brief explanation
for all to hear.
On host USC-ECLB, in one of my subdirectories, PS:<JSOL.WORKS>,
lives the complete archive of the WorkS mailing list. You may FTP this
file using the username ANONYMOUS and the password GUEST. Unfortunately
ECLB does not permit guest accounts, and AI ran out of disk space months
ago, hence the move of the archives from AI, where they used to be located.
If anyone has any trouble accessing the archives, I will be happy to
help out.
Cheers,
JSol

Whorfian Hypothesis and Programming Languages
Specialized Network Automatic Processors
----------------------------------------------------------------------
Date: 20-Mar-82 2250-EST
From: Stephen Slade <Slade at YALE>
Subject: Re: Whorfian Hypothesis and Programming Languages
The "Whorfian Hypothesis" (named after Benjamin Whorf), stated
briefly, is that one's native language determines (to at least
some extent) one's primitive perceptual and conceptual
categories-- i.e., linguistic structure determines the structure
of thought processes. The contrary view is that all human
languages have a structure determined or limited by universal
(presumably genetically programmed) primitives of thought. It's
one of those "chicken-and-egg" issues and has been studied by
cultural anthropologists for decades.
I think the Whorfian Hypothesis has little or no bearing on the
issue of how one's first programming language instills biases
that affect one's subsequent learning and/or appreciation of
other programming languages. More "mundane" psychological
theories of learning and of social psychology are more relevant
tk the phenomena.¬

supplies them, if any.) My contribution follows.
What do I want in personal workstation software? My wish list:
1) A really good editor. And I mean REALLY good. This deserves more
comment, but at least it should make good, full use of the mouse and
bitmap display (with windows and real fonts, no more of this fixed
width or helvetica junk). I spend most of my time editing in one
guise or another, so let's please have one excellent editor that is
used for editing in ALL of its guises.
2) Pleasant user interface. By this I mean one that I don't have to
wrestle with to get things done. Definitely modeless. Certainly
including windows and completely integrated into the whole system
design, see next.
3) Integrated system. A good synthesis of programming language,
database manager, and graphic software can take the place of (the now
outmoded concept of) an operating system.
4) Programmable in the extreme. The system should be programmable as
much as the user wants to program, but without the usual drawbacks of
having to to sixteen different kinds of programming. This relates
also to point 3, and implies removing some distinctions: the
distinction between system code and user code, the distinction between
interface language and programming language, the distinction between
built in things and added on things. The system should be written in
one programming language which defines the system and therefore the
programming language, which should be the same as the interface
language, which should be the same as the editing language, etc.
5) Storage allocation and memory management. A must. Not that I
would choose it, but a clever software scheme can help overcome the
hardware limitation of small virtual address. However, this is only
true if the memory mapping and allocation is entirely done by the
supplied mechanism; the temptation, as well as the need, to supply
your own should be zero.
6) Incremental compilation. Probably this means dynamic binding, but
what I really want to recompile only those things that have changed
since last the task was done.
7) Interruptible activities. The classic edit, compile, debug cycle
is not only out of style, it's out of the question. Besides being
modeless in the small the system should be not modeful in the large,
i.e., an activity should be interruptible to resume another activity
at the whim of the user.
8) Good programming support. This is a whole raft of things, such as
type checking (not necessarily in the Pascal sense), large scale
programming support, strong implementation of contemporary programming
language, good symbolic debugger, program assisting editor, etc.
9) Good metaphor for interprocess (or interprocessor) communication.
This is rather vague, I admit, but our understanding in this area is
still very limited. Parallel to the communication needs are
synchronization needs, the two go hand in hand. The important thing
here is that as much as possible the distinction between local/remote
communication should be removed. [Reply to George Coulouris' comment:
CSP may be the right model, but I prefer the weaker suggestion here
only that the two be the same. More thought as to the fundamental
nature of the issues seems warranted. If by CSP you mean as in C. A.
R. Hoare, I disagree, CSP in this sense is too much of a straight
jacket; in defense of CSP, however, I have no better suggestion.]
10) Simplicity. Too many systems have been built with the idea that
problems could be solved one at a time by adding a gizmo that takes
care of that one problem. Really good solutions inquire as to the
nature of the kinds of problems they will encounter, then combine a
few simple ideas for an elegant solution to all of them. Let's
simplify our ideas rather than complicate them, for a system that will
solve well the problems we run into in the future, not just the ones
we think of today. This way our system will be strong enough to last
a long time, and also be easier to give up when we finally do have to
change.

Subject: First languages and Whorf
A high-school buddy of mine speaks French, and wants to learn German.
I've cautioned him against it. I told him if he really wanted to
speak German, he should have learned it first; having instead started
with French, he's stuck with French. I asked, do you really want to
speak German like a Frenchman with an American accent? He called me
something with the word "merde" in it, which only proved my point. He
never heard of Whorf.
The Whorfian hypothesis is related to models of brain plasticity. The
human brain is very "plastic" during the first few years of life; this
is the time when the brain's firmware is literally being programmed by
experience and the environment. A classic experiment is to blindfold
a newborn cat for its first several months; this blinds the cat for
the rest of its life by causing atrophy of the visual cortex. With
human infants, the reverse kind of experiment has been performed --
increased stimulation and early teaching of specific skills seems to
promote specific talents. (It is generally supposed that sensory
deprivation in humans would lead to a high incidence of politicians.)
Plasticity diminishes throughout childhood, so only the earliest
experiences influence the mind's "set." Whorf's hypothesis, if true,
can only apply to what infants and toddlers learn. Beyond age 6, even
exposure to Cobol won't prove permanently debilitating (although
surgery might be indicated in later life). But if your 2 year old is
learning to program, well then, maybe you do have something to worry
about.
In a few years the kid will know more than you!

I had hoped that the current discussion concerning languages
and Whorfian theories would somehow wind its way back to workstations
but this has proven not to be the case. I believe that the discussion
itself should continue but should be moved to HumanNets where it
probably belongs.

In quantity 25, they are prices at about $900; comparison with the
price for the Intel configuration shows what a year can do in this
business, if there is sufficient projected volume for a board......

There are only two Ethernet (10Mb variety) interfaces worth looking at
right now: the 3com and the Interlan. Both have Unibus, Qbus and
Multibus versions. For Multibus, the 3com board is the winner: only
$1500. The Interlan boards have a couple of advantages over the 3com
boards: they provide fairly substantial address filtering, and they
implement the exponential backoff algorithm when transmission
collisions occur.
However, for some applications the 3com board is the only choice,
since it provides on-board host-addressable memory. E.g., for SUN
workstations, which ordinarily have no Multibus memory into which to
DMA, the 3com board is ideal.
Other than the Multibus 3com board, both companies are selling these
interfaces for around $3K. (Why anyone would buy the Intel interface
is beyond me.)
Please don't send mail requesting further information. Instead, look
in nearly any trade magazine for addresses and phones of Interlan and
3com.

I'm interested in getting one or two track balls to use experimentally
instead of mice on our Lisp machines. I'd like to know of any
manufacturers or distributors of track balls who I can write to for
information. I'd also like information on prices, quality, and output
produced (i.e., resolution, maximum speed, etc.). Please reply to me
(PGS@AI), not the mailing list, Because I'm not on it.
Thanks,
Pat Sobalvarro

Subject: Addresses for Apollo and Perq

Perq (pronounced Perk, I was told) is made by:
Three Rivers Computer Corporation
720 Gross Street
Pittsburgh, PA 15224
(412) 621-6250
and they have sales and service offices in Hartford, Washington, D.C.,
Atlanta, Pittsburgh, Chicago, Dallas and Los Angeles
The Apollo is produced by:
Apollo Computer Inc.
19 Alpha Road
Chelmsford, MA 01824
(617) 256-6600
I have seen the Perq, and in my opinion, it is a slick looking
and operating machine. It has lots of nifty features, some of them of
dubious utility (like the ability to shape the cursor in one or
several different shapes. They used this feature to have the cursor
look like a little man pushing text off the screen in full animation.)
I think that I would have difdiculty justifying this to my supeRiors,
unless they love executive toys. I know that they would never let ME
get one!
