With terminators on 1) the 2nd ports of the HP88780B
and on the 2nd
port of the KZSA I got nuthin'
This, I guess, is how it is supposed to be connected.
However, when I pull the terminators from everything, I
get:
I assume you don't have the tape set up as ID 7?
Things would get pretty upset if you did that!
Do you have any other known good SCSI device that
you can drop onto the KZQSA (on its own) to see
verify that the KZQSA itself is good? A CD-ROM drive
would be ideal but even a disk would do.

I finally pulled the tape drive off of the vax and connected it to a
Linux machine... which can't see it. I suspect either an internal
cabling problem (loose cable, etc) or bad SCSI card on the drive. I
found an old exebyte drive which I mounted in a case and threw on the
VAX and it saw it. Arrrgggh. Of course if I had tried some
relatively known working device 1st time I would have saved myself a
few hours of wasted time. But, of course, where would be the fun in
that..? :-)

Are you sure that you don't have the version of the 88780 tape drive
with differential SCSI? That was common on server systems. Note that
this is not LVD (low voltage differential), it's the original style
differential, which is now sometimes referred to as HVD.
It used to be possible to buy the single-ended SCSI board for that
drive from HP, but not any more. :-(
If you look around, you can sometimes find PCI differential SCSI
host adapters cheap.
