The board was made in 1983 WOW!!! I can only imagine that it was very expensive in those days. 1 MB on a single S100 card --- On Thu, 3/19/09, Michael Hart <imsaicollector at yahoo.com> wrote: From: Michael Hart <imsaicollector at yahoo.com> Subject: Documentation for a 256KM To: "General Discussion: On-Topic and Off-Topic Posts" <cctalk at classiccmp.org> Date: Thursday, March 19, 2009, 2:13 PM 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 Michael Hart
