An older piece of computer gear is causing more trouble than it is worth, due to a design fault in the Z80 CPU board. I have another board which, with a little playing, could probably be substituted, but I have no info on it. Does anyone have a manual (or schematics, or both?) on a SBC-100 made by SD Computer Products (Dallas, as I recall), about 1978. The thing is a Z80 CPU, serial port, and a small amount of memory. Unfortunately, someone has robbed two or three TTL chips off the board, and didn't mark what they were. Any help appreciated. A copy of a manual and schematic GREATLY appreciated (and renumerated). tnx, mknox@ngp.utexas.arpa
