See the Handbook section 10.5.9 on how to properly initialize this tape.

This is interesting.  Your NCR doesn't seem to appreciate the tape.  You
might verify that your cable is okay and termination correct.  Remember,
termination at the ends of the chain only.  The NCR will terminate itself
properly; make sure the last thing in the chain is terminated and that
nothing else is.
