EPROM BOARD, PROGRAMMER AND SOFTWARE
This paper covers the specifications for an EPROM memory board for
an LSI-11, an EPROM programmer and the software related to programming the
For long term non-volatile program storage, the EPROM has many
advantages over Core and ROM. The major ones being that it CAN be changed
should a new system be desired, and also it is not subject to parity
errors which can damage a core image.
We want a double wide, extended length DEC board to hold at least 8
of the INTEL 2708 EPROMs. These are 1k x 8 , 24 pin packages. All the
logic for reading these chips shall be on the board. In addition all the
necessary wiring for writing into these chips shall also be on the board.
This means that it must not be necessary to remove any chips from the
board to program them. It is desirable but not necessary to have the
electronics for programming on the board. A simple means of attaching the
programming electronics must be included for off board electronics.
Software for programming the chips must also be supplied. This
software is to run in an LSI-11 and must be capable of copying contents of
RAM into EPROM. Typically, the LSI-11 will have 8-20k of RAM and 8k of
EPROM. It is necessary to write up to 8k of this RAM into EPROM. The ram
will be loaded from paper tape, cassette, or floppy disk. The programming
software will similarly be loaded or else be on a separate EPROM
programming board. A simple, easy to use copying command sequence is
necessary which will allow fully loading the EPROMs in a few minutes.
A compare routine must also be supplied to compare programmed EPROM to RAM,
as a test for proper programming.
Typical Application Senario.
It is desired to update the program in an inuse robot controller
using an LSI-11. Operator removes the EPROM board(s) and puts the entire
board under a UV erasing source for the prescribed amount of time. Next
the board is loaded back into the LSI-11 (this can be a different LSI-11)
and any extra RAM or interface cards plugged in as required. The new
program is loaded and so is the EPROM programming software. In addition,
the EPROM programming electronics are plugged in as required. The
operator starts the program, and the new program is EPROMed in a matter of
minutes. In the case of more than one EPROM board, this can be done one
board at a time. Next, power is turned off and the programming
electronics and the extra RAM (if necessary) are removed. The computer is
turned back on, and the new control program is up and running.
What We Want
Unimation requests a fixed price quote on building and
demonstrating this complete unit...EPROM board, EPROM programmer, and
EPROM programming software. The hardware is to be wire-wrappped or
breadboarded, but P.C. layouts are not required. Clear schematic and
parts drawings are required, showing all part values. Software is to be
delivered in paper tape format or other suitable format which can be
converted to paper tape or EPROM itself. A source listing is also
required. A demonstration is also required. This will involve
programming at least 4k words of EPROM and demonstrating that more words
on separate boards can also be programmed. Typical program length will be
7k being loaded into 8k words space of EPROM
Unimation will supply all hardware and EPROMs, which are to remain
Unimation property. Unimation reserves the right to limit the parts
supply in the case of unexplained frying of EPROMs, etc.
Project is to be completed within 60 days after granting, Delay
past 60 days will result in a 10% penalty, and after 90 days, we reserve
the right to terminate or renegotiate the entire contract.
Partial payment schedules can also be negotiated, subject to
demonstration of meaningful progress.
