Will you please send a \TEX82 tape only to the address shown on the enclosed
sheet to fullfill a prior committment that I had made and add you charge for
this to your share of the pot when you make your accounting to us.

I told Howerton that you would wait for the next version of \TEX82 before
doing this.  You might prod Dave Fuchs for a revised tape after a week or
so.  Don will be back next week and it should not be long now before
most of the serious corrections have been made.

I will be away for a couple of weeks.

{\noindent Dear Mr. Howerton:}

This is in reply to your letter of July 20th.
We have been supplying \TEX82 tapes to a few people who have been acting
as `guinea pigs' and we are now about ready to begin general distribution.

Since I last talked with you, we have engaged an outside supplier to
duplicate tapes for us as we were finding the task extremely onerous and
it was costing us much more than we could reasonable charge.  I am
enclosing the supplier's order form.

In view of my prior commitment to you, we will accept your $\$$50 check
and in return I am authorizing the supplier to send you the \TEX82 tape.
We will not be able to underwrite the cost of the hard-copy
documentation, which is quite voluminous, so you should order this directly.

It may be a few weeks before your tape is sent as I have asked the
supplier to wait for the next update which will contain a substantial
number of corrections.

{\noindent Dear Mr. Pensak:}

This is a belated reply to your letter of June 2, 1982 
requesting a copy of Max Diaz's \TEX\ macros.

Unfortunately,
I put your letter into a file of letters that I thought could wait untill \TEX82
became available, thinking that it would be wise to wait until these
macros had been updated to work with \TEX82.  We were unduely optimistic
in June and \TEX82 is only now reaching a state where we can
anticipate giving it widespread distribution.

Nothing seems to have yet been done toward updating the Facil macros. So
the question is: Do you want the macros as-is, knowing that they
will have to be modified to work with \TEX82, or do you want to wait until
a revised set is available?  I have alerted Max Diaz to this problem but
he has not replied (he now lives in Mexico).

With the availability of \TEX82, we will no longer maintain the older
\SAIL\ and \PASCAL\ versions.  I am enclosing an order form for \TEX82 and
a brief note on the technique of putting \WEB\ written progams up on a
computer.  I would recommend that you wait a few weeks more before
ordering a tape as we are still finding a few bugs in the code.

I will hold your tape until I hear from you.  If you decide to get a \TEX82
tape, just alert the supplier to the fact that I have one of your tapes.

I have a request for your Facil TEX macros from someone who wants to use
them with TEX82.  Are you going to revise them and what shoul tell him?

I am enclosing the tape order form and the ``\TEX82 Installation Notes''
that I mentioned to you on the phone today.

Please note that \TEX82 is still not completely debugged.  While it is
possible to order a tape of the `guinea pig' version (-0.25), to get
started at once, I feel that you might be wise to wait a few weeks and ask
for a revised version with at least the more obvious errors corrected.

I am enclosing the tape order form and the ``\TEX82 Installation Notes''

Since you have had so little trouble in getting \TANGLE\ into operation,
it is hard to understand why you are having trouble with \WEAVE.  Let us
hope that the matter will be corrected when you get the latest \WEAVE.

To avoid any misunderstanding when you do order another tape, do mention
that you have talked to me about the matter and that you want to wait
until the `guinea pig' version (-0.25) of \TEX82 has been through at least one
revision.

{\noindent Dear Professor Nake:}

The report ``Essential E'' is an introductory manual describing the
display-oriented text editor that is available on one of our computers at
Stanford University. The E editor makes use of some of this computer's unique
operating-system features and so is not readily adaptable for use on other
computers. This editor is commonly used for writing computer programs
and for preparing the source files that are to be turned into reports,
memoranda and books.

The E editor is not a document editor, although it does provide some
facilities for getting a draft document in pleasing format. The primary
emphasis is that of speed, both in terms of the number of key strokes
required of the user and in terms of the demands on the computer.  E
should not be confused with a document compiler that allows one to produce
book quality documents directly for photographic reproduction.

If I interpret your letter correctly, the report ``Essential E'' would
be of little interest to you, although you might be interested in the
document compiler, \TEX, that is finding wide acceptance in the
preparation of technical papers and books.

By way of an example, in writing this present letter, I am using the E
editor to draft a computer file that will contain the desired text and
that will specify the desired format for the letter (including the letter
head).

The E editor allows me to make corrections within the lines that I type,
to move lines and paragraphs around as desired, to search for and replace
any desired construct with some alternate text, and to perform all of the
more usual editing functions with a minimum of effort. I can use certain E
commands to rearrange the lines of text that I type to make them easier to
read on the computer display but I do not have to worry about the final
line justification and the final arrangement of the material on the page
as the \TEX\ editor will take care of all such details.

Having made sure that my ideas are adequately expressed, I will then call
on the \TEX\ document compiler to interpret my commands and to specify in
precise detail the fonts to be used and the location on the page for each
character that is to appear in the final document.  My letter to you will
then be printed on a Dover printer which provides a 384-dots-to-the-inch
resolution.  If I were typing something that was to appear in a book, I
could use the Alphatype printer which will produce a document with a dot
resolution of 5333 dots to the inch.

We are currently in the process of debugging a new version of \TEX\ known
as \TEX82 which will supercede two earlier versions that have been
distributed widely.  The entire \TEX82 system has been put into the public
domain and we distribute it freely at the nominal reproduction cost.  For
your information, I am enclosing an order form and a brief description of
the process of installing \TEX82 on a computer.

I am afraid that this letter has turned into a sales pitch for \TEX82, but
then, if you are to prepare reports for a research project on document
preparation systems, your reports should be written using the best available
document preparation system and \TEX82 may just possibly be this system.  
If your aim is to develop a superior document preparation system then 
\TEX82 will provide a comparison system that you will have to exceed.

{\noindent Dear Mr.Winter:}

When I talked with someone from your organization some days ago, I quoted
cost figures for the \WEB\ and \TEX82 documentation that proved to be quite
unrealistic.  The \TEX82 document alone is over 450 pages long.  The
revised costs are listed on the enclosed order form.

If you wish to receive a tape at this time, please use this order form. If
you wish the documentation only, please make your check payable to
Stanford University and mail it to me.

I am also enclosing a brief description of the steps that must be taken to
install \TEX82 on your computer.

Please note that \TEX82 is still not completely debugged.  We are making
it available now so that a few brave souls may get started in writing the
necessary `change files' for their systems and so that a few helpful souls
may assist with the debugging. `Change files' written for the present
version of \TEX82 will probably require only trivial changes to adapt them
for use with future versions.  You must realize, however, that you will
need to order (and pay for) another tape later as the changes to \TEX82
will undoubtedly be rather extensive.

{\noindent Dear Dr. Long:}

I am enclosing an order form that you may use to order \TEX82 from the
outside service group that is now duplicating tapes for us.  Also enclosed
is a brief note on installing \TEX82 that will supply most of the information
that you requested in your letter of 21 July 1982.

need to order (and pay for) another tape later as the changes to \TEX82
will undoubtedly be rather extensive.

The additional \TEX ware programs that we are supplying, are all believed
to be in nearly their final forms.  TANGLE and WEAVE, in particular, have
been tested extensively during the writing of \TEX82 and should be
reasonably bug free.

Users who have early versions of the \WEB\ system will note that \TANGLE\
and WEAVE\ now each accept two input files, the master \WEB\ input file,
as before, and in addition a `change file' that contains the system
dependent changes that are needed to adapt the program to your system.

New York, N.Y. 10025\cr}
{\noindent Dear Mr. Rash:}

Thank you for your letter of 22 July 1982 and for the information about
your facilities.

The best source for continuing information on \TEX\ is the newsletter \TUG
boat published by the \TEX Users Group and obtainable by becomming
a member of this group.  To join, write to the \TEX\ Users Group, c/o The
American Mathematical Society, P.O. Box 1571, Annex Station, Providence,
RI 02901. with a check for $\$$20 enclosed.

\ \TEX\ was first written in \SAIL\ then in \PASCAL, and the 
latest version, \TEX82, is written in a new language called \WEB.  I am
enclosing a brief summary of the steps that must be taken to install
\TEX82 on your computer.  I would strongly urge you to acquire a \PASCAL\
compiler.  Without a \PASCAL\ compiler, your only recourse will be to
obtain a precompiled version from some other IBM installation and there
are questions as to the feasability of doing this. We supply the code that
is needed to install the two \WEB\ pre-compilers, \TANGLE\ and \WEAVE, on
your computer.

Susan Plass of the CIT organization, here at Stanford, has been acting as
`site coordinator' for the IBM 370. The `site coordinators' get tapes from
us and prepare the necessary `change files' to adapt \TEX82 to their
particular computer and then make \TEX82 available either in \PASCAL\ code
or, in some cases, directly in a precompiled form.
Mrs Plass should shortly be in a position to supply you with the modified
\PASCAL\ code for \TEX82 but there is a question as to the proprietary
aspects of supplying pre-compiled code using the IBM \Pascal\ compiler to
an organization that is not licensed to use IBM's compiler and, of course,
you would not want the precompiled code if you had the IBM \PASCAL\
compiler.  But even having a pre-compiled version of \TEX82, there are apt
to be problems having to do with the particular way in which each
different installation handles file access.

You will probably still have to write your own device driver to interface
the \TEX82 output (which is in what is called the \DVI\ format) to your
particular printer. It seems to me that the printer companies should
supply such code as a part of their promotional activities but they have
been slow in doing this.

Many users obtain precompiled versions of \TEX\ to get started and also
arrange to get tapes from us in the Computer Science Department at
Stanford to free themselves from dependence on a secondary source and the
time delay that is involved with this extra link in the supply chain.

We, in the Computer Science Department, have arranged for an outside
vendor to duplicate tapes for us.  An order form is enclosed.  Please note
that \TEX82 is still not completely debugged.  Many \TEX\ users and
potential users seem to prefer to get tapes now, even though they 
may have to order a second tape later to get a fully debugged program.
The \TANGLE\ and \WEAVE\ pre-compilers have been extensively tested and
are believed to be in their final form.

\ \META\ is still only available from us in the \SAIL\ language for which
there is no IBM compiler.  \META\ is to be rewritten in \WEB\ but
this is still some months off.  We do supply users with a reasonable
collection of Computer Modern fonts so they do not absolutely have to have 
\META\ but it will certainly be nice when \META\ is available in \WEB.

There are so many suitable printers on the market that I hesitate to
advise you. Printers vary in resolution from a very few dots per inch to
5333 dot per inch for the Alphatype.  We rather discourage the use of much
less than 200 dots per inch although there is the matter of cost involved
and many users have both a low resolution device for page proofing and a
much higher resolution device for their final output. An alternate
procedure is to use a relatively low resolution printer and photo reduce
the final output.

  Hewlett Packard recommends a two-to-one reduction with
their 2680, which is hardly in the low resolution class, to obtain an
effective dot density of 360 dots to the inch.  This letter is written on
the Xerox Dover printer at 384 dots to the inch.  Xerox seems to have
standardized on 300 dots for ther newer printers and there are several
moderately priced printers with resolutions in the 200 to 240 range, the
Imegen Imprint-10, at 240 dots, is one of these.  The Versatec is favored
by many users. Once you acknowledge an interest in printers you will hear
of many others.

{\noindent Dear Mr. Takayuki Sugimura:}

The enclosed tape is being sent in response to the letter from Yukiko
Oyama of your organization dated July 30, 1982. Thank you for the $\$$120 check.

An enclosed sheet outlines some of the steps that will be necessary to get
\TEX82 up on your computer.  This is explained in much more detail in the
relater hard-copy documentation that will follow under separate cover.

The two \WEB\ pre-compilers are thought to be in their final form.  The
\TEX82 code is not yet completely debugged.  From your letter I judge that
you would like to receive the initial distribution rather than to wait
until later.

We have made arrangements for an outside supplier to handle the
distribution of future tapes for us.  I am enclosing an order form that
you may use if and when you wish to obtain the latest version.  I would
recommend that you wait until you have the present version in a compiled
form on your computer before asking for an update to allow the maximum
time for the remaining errors to have been found.
I would like to call your attention specifically to the fact that these
tapes are being distributed at essentially their actual reproduction costs
and that an additional charge will therefore be made for the corrections
and updates.

It has been nearly three months since you last wrote me.  \TEX82 is
finally being made available for distribution but it is still not
completely debugged.  I am writing you at this time to learn of your
present wishes.

I am enclosing a brief note on installing \TEX82 that may serve to
refreash your memory as to the procedure needed to get \TEX82 up on your
computer.  If, after reading this, you would like to have a tape at this
time just let me know.

There may be one hitch.  Since it has been nearly six months since your
check for $\$$120 was drawn, there may be some question about it being
honored, Some organizations automatically stop payment on checks that have
remained un-cashed over 2 or 3 months on the assumption that they must
have been lost.  If this should be the case for McGill, please let me know
and I wiil return the check and you can then reorder using the enclosed
order form. If everything is still in order, I will be happy to mail you a
tape and the hard-copy documentation as you elect.

Our outside supplier is able to duplicate tapes at a price that works out
to be a bit less than we were charging. If you want to let the previous
order stand (and if the check is still good) I will try to make up the
difference in cost to you by seeing that you are advised of some of the
corrections to \TEX82 as they become available.

This is a belated reply to your letter of May 20th 1982.
We are now making \TEX82 available for distribution although it
is still not yet completely debugged. 

The development of \TEX82 has taken longer than anticipated and we have
been delaying action on many requests until we could supply \TEX82 rather
than the earlier version that will now be considered obsolete and will no
longer be maintained.

Since it has been so long since hearing from you, I am returning your
check for $\$$100 payable to Stanford University. I am also enclosing an
order form for your use if you still wish to obtain \TEX82 at this late
date.  As you will note, we have made arrangements for an outside
service group to duplicate tapes for us.  They will also supply copies of
the hard copy documentation.  Please note that the charge made for the
tape does not include the cost of supplying revisions and corrections when
these become available.

The \META\ program, that you also requested. is still not available in either
\WEB\ or \PASCAL\ and it would be quite useless to you in its present form.
It will probably not be available in \WEB\ for some months.

I am enclosing a brief description of the steps that are involved in
putting \TEX82 into operation on a computer.  This lists the documents
that are being made available at this time and it also gives the address

I am afraid that it is a bit impractical to get the documentation via the

{\noindent Dear Dr. Canzii:}

This is a much delayed reply to your letter of June 29, 1982.  Thank you
for your check. It has seemed pointless to send you a tape as long as
\TEX82 was still not available for export, and I have been somewhat at
loss as to how to answer your request for fonts.

\ \TEX82 is still not completely debugged but we are finally making it
available to outside organizations.  I can now send it to you if you wish
to receive it in its present form.  Please note that the charge made for
the tape does not include the cost of supplying revisions and corrections
when these become available.

This tape will contain some additional information that you may find
useful and perhaps some that you do not need.  It does contain some
Computer Modern fonts at 240 dots per inch resolution whereas the fonts
sent you earlier were at 260 dots per inch.

As to fonts, we usually limited our distribution of fonts to the Computer
Modern Font and these only in those resolutions that we have readily
available at the time.  Some of the fonts that we have available for our
own use have been obtained from other \TEX\ users and many of these fonts
are subject to proprietary constraints on their distributiion.  Computer
Modern Fonts have been generated in wide variety of different resolutions
all the way from a few dots per inch up to 5333 dots per inch, but many of
these are no longer readily available in an exportable form.

If you can specify a few different resolutions that you would particularly
like to have, I will be glad look into the problem of supplying you with
Computer Modern at these resolutions or something near
enough for test purposes.

We have made arrangements for an outside service to reproduce tapes for us
and I am enclosing one of their order forms for your information.  In your
case, please sent your request to me since you have already paid us.
The tape can be in ASCII or EBCDIC as you elect.

{\noindent Dear \TEX\ User or Potential User:}

As you probably know, \TEX82 is in an advanced state of development.  We
have arranged for an outside supplier to duplicate tapes containing \TEX82
and some related files needed to install it on your computer. I am
enclosing an order form for this service.  The charges made for each tape
are for that tape only and there is no agreement either expressed or
implied that this supplier or Stanford will provide any corrections and
updates that may later be desirable or will notify the recipients of such
updates.  The material on the tape is all in the public domain and it may
be reproduced and distributed to others.

\ \TEX82 has not yet been completely debugged. It is being suppled at this
time so that users can get a head start in preparing the necessary change
file to handle the system dependent featured that may be unique to their
installation.

\ \TANGLE\ and \WEAVE\ having been tested extensively by their use during
the writing of \TEX82\ and are thought to be in their final form.  The
remaining files on the tape are in varying states of final debugging but
they are all quite usable in their present forms and are of help in
installing \TEX82.

We at Stanford will see that the supplier has the latest version of \TEX82
and we will try to circulate information as to the state of the debugging
either via \TUG boat or by letter if the timing is such as to make
this desirable.

{\noindent Dear Mr. van Der Eijk:}

This is in reply to your letter of July 16, 1982.

We are currently delaying filling requests for \TEX\ until we are able to
supply \TEX82, which is an entirely new and much improved version that is
in an advanced stage of development.  Especial attention has been given to
the problem of transportability and \TEX82 will be much easier to install
than were the earlier versions.

Before we can advise you as to the easiest way to install \TEX82 on your
computer we will, however, need to know something about your computer
installation, and in particular the type of computer that is to be used,
its operating system,the type of output device you now have or contemplate
acquiring (with its dot resolution), and if your system supports a
\PASCAL\ compiler.

\ \TEX82 is written in a new language called \WEB. This is translated into
\PASCAL\ by one of the two pre-compilers that comprise the \WEB\ system. We
supply the necessary precompilers and information as to how to install the
\WEB\ system on your computer.

{\noindent Dear Mr. Hin:}

This is in reply to your letter of 16 July 1982.

As you may have learned from TUGboat, \TEX82 will soon be available. We
are, acordingly, holding up on the distribution of the existing, soon to
be obsolete, \PASCAL\ version of \TEX.

The new \TEX82 will be easier to use and superior to the existing version
in many respects. A great deal of thought has gone into mimimizing the
system dependencies of the code as written. The remaining system-dependent
features that cannot be circumvented are handled through the mechanism of
a relatively small `change' file.

We are planning to improve our method of distributing \TEX\ and \TEX\
related files. You will be advised as soon as these plans are definite.
Your request will not be forgotten.

{\noindent Dear Ms. Weng-Beckmann:}

I am enclosing a copy of a letter that I sent you on June 22,1982.  This
may have arrived after you wrote Mr. Trabb-Pardo or it possibly never
got to you because of my error in the way I typed your name.

Since the \TUG\ meeting is not until next week, I do not have anything to
add, but I do want to make sure that you have a copy of my earlier letter.

{\noindent Dear Mr. Roderburg:}

This is in reply to your letter of 7.7.82 to Mr. Zabala.

I am sorry to hear that you are having trouble in getting all of
the information that you need.  Perhaps I can help a little.

The problem of organizing the distribution of \TEX\ information
will be thoroughly discussed at the forth coming \TUG\ meeting here at
Stanford on July 26-27 and we hope that we will be able to do better than 
we have done in the past.  The Aarhus group had agreed to act as the `site
coordinator' for CDC computers and it is unfortunate if they have
not been able to meet your needs.

As you may know, Don Knuth has completely rewritten \TEX\ in a new
language called \WEB.  This new version, \TEX82, should be much easier to
use than was the earlier \PASCAL\ version.  A great deal of attention has
been given to the problems of transportability.  The two \WEB\ pre-compilers,
called \TANGLE\ and \WEAVE, will accept locally generated `change' files
that compensate for the detailed ideosyncrasies of different computers and
different compilers.  Once a user has a set of change files, for his
particular combination of compiler, computer, and operating system, he
will normally be able to use these same change files with new releases of
the master programs with little or no modifications.

\ \TEX82 will soon be ready for distribution and we will also make available
full information concerning the new \WEB\ language.  We are planning to
have a standard distribution tape that will contain:  1) a special
`characters' file that displays samples of all standard characters as
written on the tape, 2) the \WEB, \PAS, \TEX, and \DVI\ forms of \TANGLE,
3) the \WEB\ forms of \WEAVE, \TEX82, \DVITYP, \POOLTY, \TFTOPL, and
\PLTOTF, 4) a few typical `change' files, 5) the {\mc BASIC.TEX} and {\mc
WEBHDR.TEX} files, and 6) a representative collection of \TFM\ and \PXL\
files for many of the more useful fonts in the more commonly used resolution.

The problem of matching the output from \TEX82 to all of the different
types of printers is a difficult one, but fortunately many groups are
using Versatecs. We do not seem to have as many users with CDC computers
as with some other types but several of these are in Europe and by
exchanging notes you should be able to devise a \WEB\ written driver that
would require, at most, a small `change' file for each individual
installation.  Perhaps the CDC Users Group might be an
appropiate organization to look into this matter.

\META\ is currently not available in an official \PASCAL\ form although I
understand that some users have their own versions.  The next major task
will be to write \META\ in \WEB.
