MP-8M Memory Board
The MP-8M Memory Board is a 5 l/2 inch x 9 inch board with a total storage capability of 8,192 (8K) words of a 8 bit random access memory. The circuitry on the board provides all of the address decoding and data line buffering to handle a total of 16 4K (4K bit x 1 bit) static random access memory integrated circuits. All interconnections to the system are made via a 50 pin connector to the Mother Board (MP-B). Current consumption for the entire board (8K of memory plus decoder/buffer) is approximately 1.5 amp.
Introduced by Southwest Technical Products Corporation in 1977. The MP-8M kit cost $250.
