If that's true, then I'm running on magic.  I have a SCSI drive on my 3B2/600
and don't have the NSU installed.  Go into firmware and do a 'filledt' then
run 'dgmon' and do the following:

dng scsi ph=17

This will run phase 17 diagnostics and will tell let you know of any scsi
conflicts and if it can see all the SCSI devices out there.  After running
dgmon, do another 'filledt' and generate a new unix by running '/etc/system'.
This will create the devices if they don't already exist for your tape drive.

Also, 'prtconf' as super-user would let you know if your 3B recognizes the
tape drive.
