Today I picked up about 180 or so of these boards. I believe they might be
from the 60s or thereabouts. I couldn't find a
datestamp on them but they
don't use ICs. Instead it looks like they use the
old gold-wired
transistors. Not all of the boards are pictured but there were many
duplicates so I probably got at least one of each kind.

In the same lot I picked up some DEC boards. These I would be looking to
sell. They were tossed around and not handled properly so some may need
repair or would just be for parts.

Can't say much about the purpose, right off, but the card cage, if it's
part of the same lot (and it appears to be), contains some Solid State
Scientific, Inc. (SSS) SCL 4000-series CMOS ICs with a date code of
1975. SSS persisted into the 1980s until it was purchased by the Penn
Central holding company and merged with Sprague.
So you've got a "not earlier than" benchmark.
I wonder if these are part of some control or security system.
Definitely not comptuer, given the date and technology. Kind of nice to
see those little red mica caps again.

Actually that board you called a card cage doesn't go with the rest. They
don't fit and the contact spacing isn't right. Sorry about that that red
herring.

Okay, that threw me off the trail. Scratch that guess.
The odd mounting of the TO-5 transistors points to a fairly old board.
but I have no idea what the boards might be to. Perhaps the mounting
will ring a bell with someone here. The telco manufacturers had some
pretty odd ways of mounting transistors, but I don't know if these are
them. I wonder if the mounting is an approach to anti-vibration; that
might point to a military application.

I think the Printronix boards are from line printers.

I doubt it very much. The modern CSC dates from 1962 as strictly a
software outfit. At any rate, the logo at that time was a stylized atom
with "CSC" above it.
"CSC" can refer unfortunately to a lot of things and this CSC may refer
to nothing more than the place that fabricated the boards, not to the
actual customer.
Perhaps this stuff isn't from a computer at all. Probably a good idea
to analyze the components on each board and take a stab at the function.

It looks like the DEC boards are 4 M7264s LSI11), a M7270 (LSI2), 2 M8044
(MSV11-DD), and a few compatables.

Here's what I've got, at least I think these are the only actual DEC cards.
DIGITAL M8045 Memory Board
DIGITAL M8045 Memory Board
M7264s LSI11 Flip Chip Board
M7264s LSI11 Flip Chip Board
M7264s LSI11 Flip Chip Board
M7264s LSI11 Flip Chip Board
8009, memory board? - Green handled board
DIGITAL M8186 CPU Processor Board
MSC 4601 303-0171 Memory board? White handles, one is half broken
DAC-II board, Andromeda Systems? Has 4 DAC80-CBI-V Chips
These two are pretty much considered sold:
The red handled one says M7954 on the back of the PCB. It has 737C stamped
into the back of the handle.
The white handled one says 700-0086 and NDLV-IIJ/2 on the back. It has
Calmark 110 on the handle. The front of the board says netcom products, inc
NDLV-IIJ/2 700-00871
I have an offer on the 2 large and 1 small prototyping board, still
awaiting payment though.

I'd say the card cage is of a different era than the boards, the boards
look to be of early-60's vintage. Looks like a date code of 6252 or 6232 one of the power transistors. There are likely to
be date codes on other
parts such as caps, trimmer resistors, transistors, etc.
