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.

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

Definitely
not
comptuer, given the date and technology. Kind of nice to see those
little red mica caps again.
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.
