   Or am _I_ confused?

   Other than CPU speed, I'd guess that a 30/40 was more
likely to have an ST506/SCSI card, and a 38/48 was more
likely to have a SCSI/SCSI card,  (Especially prized are the
early ST506/SCSI cards, which had all the parts needed
(except, perhaps the connectors) to use RD-series (MFM) hard
disks.  Of course, those may now be even harder to find than
SCSI floppy drives.)
