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?
