    Can anyone identify these boards? Person I got them from can't remember

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.
