The appropriate devices should be /dev/rct8 (rewind at end) and /dev/rct12
(no rewind at end).  When accessing non-SCSI cartridge tape drives using
Unix tape utilities you must issue a tape rewind command after inserting
the tape (even if it is already physically rewound).  This can be accomp-
lished by either of the following commands:

    /usr/apollo/bin/mt -f /dev/rct8 rewind
            or
    /usr/apollo/bin/rbak -dev ct -rewind

If this is not done, you will get a "No such file or directory" error.
