I've been using a driver I cobbled together for about a month now.  It
works pretty well, in fact.

I've been meaning to make the code available except that I'm encountering
buffer overrun errors on the DSIU port of the z50 which I cannot seem to
eliminate (thanks to the 1-byte buffer on the DSIU port - blech!).  Most
problematic if the machine is doing something while you're moving the
mouse cursor (e.g. PCMCIA activity w/ my MicroDrive).

I've tried setting the interrupt priority of the DSIU to that of the other
BIO devices in the system and was met with little improvement.

I haven't bothered hacking my driver to request resend of garbled packets
since my preliminary attempt seemed to worsen the problem and I haven't
had the time to look at it further.

Any suggestions on what to do?
