That is certainly a part of a core memory system, made by 
Electronic Memories.  Does the other side of the board have 
a core plane on it?  Memories from that vintage often have 
multiple boards, with select drivers, sense amps, inhibit 
drivers, decode logic and timing, as well as the core planes.
