You can probably make it work, although I wouldn't do it with MY data.
The first problem is that the Mac uses ID 7.  This could probably be
gotten around with a patch to the SCSI Manager.

However, there is a more serious problem.  Does Apple do arbitration?
A single initiator SCSI system is allowed by the ANSI standard to skip
the arbitration phase.  It can just go right into selection.

If Apple does this ( and I think they do, at least on the plus ), you could
have serious problems if both Macs try to access the bus at the same time.

If you are willing to rewrite the SCSI Manager, of course, you can get
around these problems.
