- The "mt" command does not work with the 9144A, 9145A, 35401A and similar
- HP-IB CS/80 tape drives because they are not treated like classical
- serial-access devices. These drives are actually block-rewritable random-
- access devices - very slow disks you might say.

- Any "append" operation that would work on a /dev/rdsk will work on these
- tape drives. "mt" operation attempts often result in "not a typewriter",
- one of the less helpful Un*x error messages.
