Hi Ruud,
regarding your comments on the timing of the IEEE488 bus,
you may want to look at the VICE IEEE488 emulation. It has
a IEEE488 state engine that monitors - in VICE - the emulated
port lines of the PET and - in my lptiec - the IEEE488 lines
of my original PET and uses the VICE drive emulation as
"backend". It does not use any artificial delays at all, but
only reacts on the line changes, and even better, it works
with all PETs, not only 80xx. (the 3032 was especially dirty...)
