Solid State Music - 8K RAM
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.
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.
The manual for
this board can be obtained here.
