Correct, I meant the 16 or 32 track drives.
There was a document floating around called 'hcdvsqic.txt' that I had recently
uploaded to
http://bitsavers.org/pdf/hp/tape/9144
I just found a more detailed document written in Jun, 1989 on the subject that I'm
about to upload

There are no EOT BOT holes on the HP tape, and the drive locks
I assume you mean the HP9144 and HP9145 drives/tapes. The
HP9142 uses normal QIC24 formatting and does have the optical
