Hello everyone
Does any one know about or have documentation to the
S C Digital MODEL - 256 KM
256K/1M RAM board.
Mine is populated with 256 K dynamic RAM so it has 1 MB RAM.
I don't have documentation so my attempt to repair it was to replace all the DRAM on
board.
that did not work. The parity error LED stills comes on. So in my attempt to repair the
board I definitely need the documentation.
Given that I remember something about issues using DRAM card on early S100 cards. I am
guessing these SC Digital solved the problem since the board was made as best as I can
make out on the silkscreen in 1988
