Piiceon - SuperRAM 4

This board had bank select capability and an optional parity bit.

This was a 64K dynamic RAM board with according to their advertisements, parity error detection. Since there are only 8X4 rows of dynamic RAM I am guessing the connector at the top of the board is for parity correction. 
 
I do not have a manual for this board if anybody can provide one I will update the entry for this board.
