CBMctrl dir 8 uses the standard IEC protocol, so if that does not work,
then it's not a protocol timing issue. And, IEC (at standard speeds) is
pretty relaxed, so cable issues should not be a cause.
I assume the OP is using the same cable as works on the 64. In that
case, the only think I can think is that the 64 I believe has pullups on
the data lines, and so does the drive. But, ZF does not. So, if the
drive pullups are bad, that may cause an issue.
