As has been griped about in the past, I went on an all
out google search
for
a 5.25" drive married to a USB adapter. Thought I almost had one when I
saw
a picture on the Teac website of what turned out to be a USB to IDE
adapter
they sell.
TEAC has a 5.25" SCSI drive, FD235-.....
Adaptec has a USB to SCSI adapter, so that could solve your problem
