The only reason I can imagine it should not work is addressing the
boot-image from the boot-prom.

Or else, it should not be called scsi...

When you look inside a 712, you should expect heat problems with the drive.
Its mounted in polysterene foam, also known for its perfect heat
insulation...

Hence, if you expect or experience heat problems in a 712, you can remove
the insulation and create real mounting brackets.

btw: all my ideas, not physically tested.
