Do you know anything about "storage cards"
made by National Memory
Systems? There's one of those stuck in it. Assy # 980100996.
I don't... I'm sure someone else here does...
Here's a list of what else I found in it:
M7954 GP-IB interface
M7270 LSI-11/2 16 bit CPU (2 of them)
M9400YA 120 Ohm terminator w/ refresh and floppy boot
M8400CF 16K word 16 bit MOS RAM
M7940 Serial Line Unit (SLU, Async)
M7946 RX01 floppy disk controller
M7264 11/03 Proccessor w/ 4K work MOS RAM.
Three processor boards?! You only need one...
Here's a list of the docs that I got with it:
Introduction to RT-11 (missing some pages)
Informer Computer terminal model D-301 Maintenance manual
DECLAB Fortran Extensions User's Guide & update notice 1
LSI-11 WCS User's Guide
RT-11 Software Support Manual
RT-11 Documentation Directory
RT-11 Fortran VO1C
Which version of RT-11 are the docs for?
I have a couple of more questions. What did they use
the GPIB interface
for? Is it just an instrument interface or did it connect to some of the
system devices like it did with the PET and HP computers?
It is an instrument interface... whether one of those instruments
could be another computer, I don't know...
Are the LSI-11/2 CPUs needed in this system or does the
11/03 processor
replace them?
Depends on your needs... the 11/03 has memory, the 11/2's don't. The
11/2's take up less room. Both need a console interface board.
Is there any reason to have to 11/02 CPUs in it?
You listed three... but no, no reason for 2 in a *working* machine.
But the person who you got them from may have simply put them in the
backplane to prevent damage, in which case it doesn't matter what's
in it...
I didn't get a powe supply with this, can I make
one up using the
voltages shown on the card cage or is there anything specail that I need
to know about? Do the voltages have to be applied in a certain sequence
or anything like that?
What kind of backplane did you get? Someone here may have a spare
so that you can get it working... Other than that, you might be
able to get it working if you cobble something together...
