Tape drive out to lunch

It sounds like a hardware problem, but I can not make much of an
evaluation, without knowing what is in your unibus slots, and in
which order.

If you can figure the offset, and examine the tape controller
status register, it may tell you something. Also, you don't say
what handles the lp, an lp-11 or what, need to know more about
your hdwr.

If you try to examine the tape controller registers, and find
that it is not out there, you will have learned an important fact.
