Hey all --
A straight TI 980 (not one of the later 980A or 980B variants) appeared on
my doorstep this afternoon. While well-shipped, the person I got it from
decided to ship the boards and power supply separately from the chassis --
and unfortunately didn't document where anything goes.
There is precious little information out there about the original 980 --
anyone sitting on any documentation? Anyone know someone who has one?
(Anyone have any spare parts? The core memory boards & chassis are labeled
well enough for me to see that I'm missing one of the "DA" boards...)
Thanks,
Josh

Thanks. That looks like a 980B to me. Here's a couple of pictures of what
I have (note that the boards are placed mostly randomly right now, just for
safekeeping):

Interesting. Unfortunately, I have no docs (outside of what's on Bitsavers).
Mine is the later 980A variety, FWIW, with fat TI4060 DRAMs not core.
I only recently got a console key for it.

The only spare parts would be some memory boards. I'll have to pull
them out and check them, but definitely DRAM and I think 8K or 24K
capacity, and I have no idea if they work on all variants or just
specific models. No spare I/O or CPU boards.
I was just glancing over at the docs on Bitsavers to see what it might
take to write a memory tester to toggle in. Nothing exhaustive just
simple write-read-compare testing. I know nothing of the architecture
so even that would take me a bit to figure out.

I'd be interested to see pictures of the card cages. I know what a 980B
looks like and it's a significant revision from the 980 I have here -- the
CPU is condensed from 13 or 14 boards down to four or so. I haven't been
able to find a picture of the 980A's insides, curious to know how it
differs.

Somewhere I have a couple of very short programs I hand-assembled to test
out my 980B, I'll see if I can't dig them up... I suspect I left them on my
old laptop.
Thanks,
