RE: Serial IEC bus for PETs

perhaps this is an area for Ruud's XIEEE adaptor...

if the protocols were simple and well defined, and the adaptor also "fixed" 
with respect to specification then it should also not be very hard to
interface this to the 64HDD emulator or other such drive emulation program
(eg Ruud's PC-DISK).  If this were possible then it would eliminate the need
for the special serial "driver" on the PET and compatibility would be
increased... unfortunately my PET doesn't talk to its 3040, but never had
time to diagnose whether it was a drive or computer problem....
