My Ultra SCSI DLT IV "looks" like it has the centronics SCSI-I connector,
but it is certainly using SCSI-II commands.  Connectors aren't a good way of
determing the SCSI type.

Were all of these older Sun boxen using "standard" SCSI I or II?  I've
noticed that lots of the Sun machines seem to have kinda krappy SCSI
implementations, even compared to that old 8 proc Sequent 386/486 machine.
According to the docs, that SCSI bus was capable of 8MB/sec with
differential SCSI-I.
