I think he's asking about "laboratory modules" -- the *original* DEC
products from 1957 or so. You snapped the lab modules into a power
backplane (power supply was one of the "DEC Building Blocks") and
connected the logic elements via patch cords.
The power pins aren't documented in my 1960 dec logic handbook, and they
don't seem to be documented in Bell's "Computer Engineering" either, so I
assume you need to find a "DEC Building Blocks" technical bulletin or
reverse engineer one of the lab modules -- this might help:
