This was a very nicely laid out 8K RAM card. No remarkable features except perhaps the liberal use of voltage regulators -- with no cooling fins.

SSM 8K RAM    

The board used low power 500 ns 2102's. One dip switch controlled the number of wait states to be added fro RAM R/W cycles. The other set the board bloc address.  Memory protect could be set in increments of 256,512,1K-8K also with the dip switches.  On the top left hand corner was a connection for a battery backup connection  -- something not seen on most RAM boards.The instruction manual and theory of operation was excellent. SSM had outstanding technical manuals.
