The situation is more complex than that. There are *TWO* versions of the
FC-1 SCSI interface that is attached to the FD-235 floppy drives. The
FC-1-00 is the "Teac standard" version, and I have seen a revision "M".
The FC-1-01 is a "Motorola special" version which was designed to
emulate another drive that Motorola already had drivers for. The two
differ particularly in their Mode Select parameters, but there may be
other differences. The complete part numbers are, I think:

	FD-235HS-300, FD-235JS-400  (Teac version with FC-1-00)
	FD-235HS-301, FD-235JS-401  (Motorola version with FC-1-01)

I have also heard rumour that the 00 version is not available in the US,
only the 01 version.
