Has anybody had timing problems using the CP/M Softcard? I have built the II+ revision RFI clone and have full documentation for both motherboard and Softcard. Whether CP/M 60 boots or not depends on tolerances of many chips on the: motherboard, +16k, Softcard, and even VIDEX card. Some configurations work. The problem occurs while booting, it is hard to trace anything. Some people say, that the Softcard has a critical timing. Does anybody know what measurable signal is critical, or has anybody had a similar experience? -- Peter Pavlik (U of Waterloo VLSI Group, Waterloo Ont.) {allegra,clyde,decvax,ihnp4,utzoo}!watmath!wateng!ppavlik
