Is anybody able to identify the following board? It consists of a stack of two core planes and great strips of diodes. The eight transisters present are motorola devices marked SM2824. The board itself is stamped "E2000 Memory", "52 by 52" (52 by 52 cores?) and is dated "? 18 1969".

All the component pieces have SM prefix part numbers. The only sign of a company logo is a stylised "BN" on the PCB. The edge connector is 32 + 32.

It's about time I gave my tired desktop a RAM upgrade...
