The first one is interesting because it has a list on
the right side that
appears to be a list of memory locations and op codes. It's hard to see in
the photo but the first column is labeled CNT. (count?). Most of the ICs
are dated 1972. The only other markings on the card is "TERADYNE A 794" and
"Made in USA".
Maybe from a Teradyne RAM tester? They had some big computer looking
machine that was for testing RAM, IIRC.
The second one is a core memory board that I *think*
may be for a Data
General computer. I picked up several of these and they're all made by
Dataram Corporation and appear to date from 1972. Their part number is
3010290. I took the cover off of one. Man, the cores in these are tiny!
Hmmm, the Core Memory board I've got that _I_ think is for a Data General,
is square, that looks more rectangular. Well, I just pulled out my DG Nova
doc's, and the board would in fact be square, and there would only be two
card connectors.
