How were 32-bit minis built in the 70s/80?

I can remember back in the early 70s picking up some surplus PCBs with plain 7400 (not LS) logic, including a couple of 74181 ALUs and a 74199 shift register, both in 0.600" 24 pin DIPS--and lots of SSI TTL logic. I was mostly interested in scavenging ICs from the thing, so I never figured out what the PCBs belonged to. On the other hand, I have a couple of Eurobus wire-wrap boards outfitted with lots of 10K series ECL. It appears to be a 12-bit CPU, complete with memory and registers. The clock on it is 40MHz. I don't know what it could have been. Mostly, I consider the boards to be a source of gold-plated wire-wrap pins. --Chuck
