 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:

I have here in my hands a 4-page "Specifications/Prices" sheet that
is titled "DEC Digital Test Equipment" and covers the building blocks.
But not in enough detail to determin pinouts.  It is dated November 1958.
