Hmm. If I don't delay at the host end, the other end loses chars, even in
asm. But that might just be buggy drivers. Also, on transmission from c64,
just waiting for 'buffer empty' on the 6551 doesn't seem to be sufficient
without also adding a delay between checks. But I will upload my code soon,
so you can laugh at my errors ;-)

I should try blanking during host communication as well as during drive
communication. I spent a few hours trying to fix my drive communication
before I discovered that certain Kernal routines I was using were helpfully
re-enabling interupts and leaving them on! Grr..

Cool. What toolkit were you planning on using for the UI? I
switched from Perl to Python for all my scripting about a year
or two back, and have not regretted it. Now I'm just waiting
for wxPython (the Python binding for wxWindows) and pyOpenGL
to get up to speed under OS X, and I'll be a happy camper :)
