I haven't seen one, but what I have heard is that the Apple 40MB tape
drive is slow, slow, slow.  For "super reliability" it writes everything
three times on the tape, cutting the speed by a factor of three.

There is a slim chance that when the SCSI tape support is released, it
might work with third party tape drives that provide higher speed and
better price/performance than Apple's.  But only if you, the customers,
demand it.

Our Mac-II is ethernetted to a Sun with both cartridge and 6520 BPI
magtape anyway.  The more serious problem is that they left *dump* and
*restore* off the Unix distribution!  We have to do backups with tar,
which doesn't support incremental backups.
