Ok, here is a bit of my MacSCSI code. This will add a customizable icon
for your MacSCSI. A get info for the disk (and other places) will say
"SCSI" instead of "AppleTalk" for "Where".  Note that I use Megamax C, so
you may have to do some hacking to get back to Aztec C.  To re-customize
the icon you will have to create the icon, decompile it with REdit, and
edit the resulting hex back into the following code.
