I have no idea what this is, but it sounds like it's
made of discrete-transistor logic, and LOTS of it
Would be a cool find just for all those boards,
maybe something one could build something really
old-school out of (like the guy in Pittsburgh who
built a 4-bit discrete-transitor CPU in 1968 out of
a lot of scrapped logic boards). It doesn't sound
like you snagged it, though. :(

I got a call from a scrap place today and I made a
quick trip out to see
what they had before the hurricane hits (it's due to
cross DIRECTLY over
the place's location so I don't expect the stuff to
be there come Sunday AM
since most of the stuff is out in the open). Got
some DEC core memory so
the trip was worth it. One of the things that I
found was a "Logic Rack"
made by (somebody) Research & (something). Sorry to
be vague about the name
but I was in a hell of a rush. Anyway it said that
they were a division of
XEBEC. The rack was ABOUT 8" or 10" thick and ABOUT
32" wide and ABOUT
seven foot tall and had HUNDREDS of small circuit
cards that plugged into
it. None of the ones that I saw had ICs, just glass
diodes, trqnsistors and
resistors. The cards are 4" long and 2 3/16" wide
with a 16 position CINCH
contact on one end. The transistors that I looked
at were all date coded
1969 but I saw what looked like it might have been a
date on the rack that
said 1973. Anybody know what this is?
