This reminds me the 5 boards that were in the back of my Uniservo 10/14
and which were the terminators (to put on the last tape drive connected
to the main controller). Maybe these boards have a similar function?

I checked and they are no GE 4000 system boards.

anything about them.

Date codes of 1964. Size 4.5"x3.25". Looks like used card edge for
keying but has separate 23 pin connector for electrical connection.
No useful markings I can see. Has card ## on the back.
Search by picture didn't find anything.
Thanks
They remind me of RCA bizmac boards, which are likely to be related to
GE, as that computer division changed hands a number of times.
The connectors are Elco Varilok.
