The Quadra either uses a different processor (if you don't upgrade it)
or does not meet Apple/IBM standards for Power machines (yes, really).

Many people seem to have missed my sarcasm.  So far, no one has
pointed out any 'advantage' to SCSI-II over everything else for
CD-ROM.  Any advantage people claim for SCSI-II also seems to apply to
SCSI-I.  Transfer speed isn't exactly an issue when you're dealing
with CD-ROM and, while SCSI-II does provide a more standard command
set (by expanding the SCSI-I set), many devices which 'claim' they are
SCSI-II aren't and SCSI-II is a *lot* more sensitive to cable quality
-- to the point where things that work in a SCSI-I setup will fail
with a SCSI-II controller.
