This was an "essntial device" in my younger engineering days. Sigh.

Very nice, great find. That wire wrap tool is identical to one my dad had in
his CE toolkit (now lost
unfortunately). Are there any other markings on it apart from the IBM p/n?
That would make sense if these were OTP or fused parts.
Wouter, can you check the pins with an ohm meter, to what we think are power

I recently won a Univation Intenral Hard Disk System for the DEC Rainbow

But it came with the wrong docs and no diskettes.
Any chance that anybody has anything in this area squirreled away somewhere?

They look like it, with a right-angle adapter plugged into the end.

are these extender cards for IBM MST modules?
Maybe they are OTP?

Armed with that and the fact that pin 1 connects to the leadframe I
figured maybe it's something like the 6830 Mikbug prom -- 0V on 1, 5V
on 12, data on the left, address on the right. Tried reading it like
