Hi, I don't know if you saw the SC/MP LCDS (Low Cost Development System) for sale on eBay (Australia) last week, but I bought it. I've been looking for one of these babies for a long time, and to find one for sale near where I live was too good to be true. Indeed! It's dead. Hehehehe, but it has all the parts and manuals, schematics and ROM listing. So, I guess I'm going to be busy in the next few weeks while I try and trace the fault. It's getting the right voltage, so I am assuming it's a bad chip or a ROM has gone bad. I'll get the CRO onto it and try and read the ROMS to find out what's going on. It came with both a SC/MP I and a SC/MP II processor card. Neither card works in the system so I am assuming it's a main board fault. I got a homebrew SC/MP system and some spare CPUs so I can chop and change and hopefully get this old system running. I'll let you know how I go. river
