When you get your machine, take a look in /sys/data/scsi_data.c.
There's a large comment in there with general instructions for adding
devices.

I'm not sure about availability in OZ, but here in the US Digital sells a
QIC tape drive called the TZK10.  If you don't have a QIC drive already,
you might want to check it out.
