Well, as Murphy would have it I just threw out a thick folder of Protec docs & literature. But, if it's the same Protec in Quebec who did indeed make Z80 SBCs in the old days before they specialized in KVMs, they're still very much alive; why not try a phone call or e-mail. www.protec.ca Protec Microsystems Inc. 297, Labrosse, Pointe-Claire, Quebec H9R 1A3, CANADA Tel.: (514) 630-5832 -------------Original Message----------- From: "Robert Collier" <rdcoll(a)hotmail.com> Subject: Protec PRO-83 Computer - More Info Hello all, I did a little more reading and found out that the model number for the computer was PMS 100. I could still use any information anyone might have - and hopefully, the model number might help. The machine is the Protec PRO-83 z80 Single Board Computer. Thanks.
