Let's not forget the difference between Differential SCSI, as implemented on
the RT and several minicomputers, and Single-Ended SCSI, on the PC, Mac, RS/6000
and other workstations.  They are not electrically compatible; the only difference
which I understand between them is that Differential SCSI allows longer distances
(the RT SCSI disks were in racks external to the cabinet).

I've heard that there are 3rd-party converters (black boxes?) which allow these
to be intermixed, but have no experience with them.
