Maybe--it was an 8 bit mini, so not very powerful. Mostly used in what
we'd call "embedded" applications. Pre-microprocessor days.
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.
