8K Static RAM Board
This looks like a relatively straightforward S-100 static RAM
The board utilized the standard (at the time) 1KX1 21L02 RAM chips.
The board recognized the Phantom S-100 line (pin #67). The board
itself could be addressed to any 8K boundary in the 64K address space.
The rather simple but adequate manual with the schematic can be obtained
