I was rummaging in the attic looking for my IBM 1130 listings, and came
across this Interdata 7/32 C Maintenance Manual. It includes detailed
schematics of the CPU, and the microcode listing. Is anyone interested in
scanning or copying this?

What chips are used for the cpu part ?

Being an Interdata model 70 owner, I would say
likely good ole TTL '181s for the ALU, just like
the the pdp10/10-20. I doubt that the 7/32 had
2901's or anything close to bit slice back then..
My model 70 uses TTL fuse proms for ucode storage-
everything else looks like 4 bit wide straight TTL series.
Isn't the 7/32 one of the very few machines that K&R
ported Unix (v5 era) to ?
cheers

I didn't look that closely last night, but I seem to recall that the 7/32
used gates and 4-bit-wide MSI parts. I don't think there are any bit slices
in there. IIRC, the CPU took up 3 15" square panels, and the next board was
the DMA controller or something like that. I'm going to send the manual to
Bruce Ray to be scanned, then I think Al Kossow will put it up on his web
site.
