Looks like Conner's version of the HP T4000s, which is actually a QIC
standard (3095).  I posted fairly trivial patches for the HP a few
months ago.

Essentially all that was required was setting the PF bit in mode
select, but there's no reason to suppose that Conner's SCSI
implementation will have the same quirks as HP's.

Incidentally, I would interested if anyone else is successfully using
the T4000s, since I having trouble reading tapes which is most likely
a hardware problem, but I'm not certain.
