I've discovered that on both the pmax and vax ports, running on
a DS3100 and Vax 4000/60, respectively, HP 35480A DDS DAT drives
aren't probed.

Both machines are running 1.5Q kernels.

The drives are recognised by the BOOT ROM on both machines, and
the drives works wonderfully under VMS on the VAX.

Is this an issue of tape support under NetBSD on the ncr controller?
I am able to probe a TK50 on the VAX machine, with an interesting
probe messages:

st0 at scsibus0 target 7 lun 0: <, , > SCSI1 1/sequential removable
st0: rogue, drive empty

The HP DAT is at target 4 in this example... it was totally skipped.

Is this lack of support for the HP drive a work-in-progress, or
a "feature?" :)
