Wameco - 32K RAM Board
This was a nice clean well laid out
S-100 RAM board.
The board came out in 1981 so it had 24
bit address decoding. It was addressable or any 8K boundary. Up to 4 wait
states could be placed on the XRDY or PRDY lines for slow RAM chips. There
was bidirectional bussing on either the DI or DO data lines so two boards could
be used for a 16 bit bus. Interesting hefty voltage regulators with carbon
voltage dropping resistors! The board was actually made by MIKOS
engineering -- the group that also made Solid State Music boards.
The manual for this board may be
