Apple is using the Quantum 80 megabyte drive with built-in SCSI
interface for the Mac II. You have to tweak the SCSI disconnect
timing to be somewhat out of spec for it to work properly, and
the procedure for doing this with the Quantum drive is probably
not universal.
I don't agree that an integral drive/scsi controller is the best
setup. A separate controller can accomodate two drives. A
separate controller gives you additional flexibility in choosing
RLL encoding, a buffered controller that can handle an interleave
factor of 1, etc.
