Do the modules look like they'd plug into a Q-Bus or Unibus backplane? If
so they can't be much older than about 35 years old I believe (if that).
DEC itself I was started in '58, IIRC. Joe's book might have some of the
info you need, there are a whole slew of Logic Handbooks from the late 60's
through the late 70's (towards the end they changed the name).

John,
This is a hell of a coincidence! I JUST posted the message below to a
fellow CC Lister. The book is dated 1971 so it may not cover what you're
looking for IF your modules are really 45 years old. Unfortunately the
book is really more of a catalog so there's little pin out info except
for some of the flip chip modules.
"I found a copy of "Digital Logic Handbook 1971" while cleaning around
here today. Digital as in Digital Equipement Corp. Need it? It seems to
be a data book of modules (M series Logic Modules, W series Special Purpose
Logic Boards, A series Analog modules, Lab Series and K Series Control Logic
modules, etc."

Anyone have information on this product series?
The 'dec Lab Modules' are 45 years old so on
topic. What I'm looking for is the pin assignment
for the backplane (only 5 jacks at this stage)
All I know is that -15v,+10v,+10v and -3v are
supposed to go in (I think) but I don't know where.
