I don't have any problem programming other EPROMs on the faster
system, but the 68764s seem to be special. I'd also be interested in
seeing what version of the software you have. ( I have Version 1.08.)
One odd thing is that with the 68764s, a "Pulse count 1" displays for
each byte while programming and eventually scrolls the display. On
the faster system, it displays a single "Pulse count 25" and errors
out.
The other thing is that an erased EPROM will not read correctly on
the fast system (gives FFs, with F3s and F7s interspersed), but reads
fine on the slow system.
Too bad that M2L seems to have vanished--it's a good programmer.
