Can someone here tell me what "differential SCSI" is, and how it's
different from the SCSI I'm used to on Macs, {DEC,VAX}station 3100s,
Adaptec 1542s, and Suns?

We've got lots of IBM Athens 400mb drives, some of which would be nice to
attach to our {DEC,VAX}station 3100s, and some people are asking about
attaching DEC RZ53s to the IBM SCSI controller (yes, I know that the
AOS 4.3 SCSI driver seems wedded to the weirdness of the Athens drive--
I'm concerned with things I have no control over like hardware
incompatibility, and not with presumably tractable driver problems.)

Is there really an electrical problem here?  Can someone accurately
characterize the issue as a compatibility problem or not?
