Macrotech MRS - 2 MG RAM Board
This was one of the few high density RAM boards made for the S-100 bus. It
came out in the mid 1980s and was a 6 layer PC board.

The board was claimed to be compatible with all S-100 systems. It was
IEEE-696 compatible. It had 120 nsec dynamic RAM chips and a LSI
dynamic RAM controller circuit that Macrotech claimed really made the board
look like static RAM. The board could be upgraded from 256K, 500K, 1MG
or 2MG of RAM depending on the RAM chips used.
I do not have a copy of the manual for this board. If you can share one
please let me know.
