I'm not sure. It may, but Ultra SCSI drives often have different
connectors on them; I don't think you'll have room for the adapter in
the 7200 case.

Yes. The internal SCSI ports on the 72/3/5/600 (and 8 and 9 versions of
those) are all SCSI 2, which differed from SCSI 1 in only a few details,
the most important of which is bus speed.
On my 7600, the internal SCSI chain is SCSI2 and the external is SCSI1.
SCSI2 devices work perfectly fine on SCSI1 interfaces.
Then there are the weird ones Differential, Wide, Wide Differential, and
Ultra.
You'll often see Narrow SCSI which is only marketing speak for SCSI1 or 2.
