	I just finished backing up a 142 Mbyte Disk through a ribbon
cable connected to the drive on one machine and a controller on another.
The cable was ~20 feet long.  When connected normally the cable length
is about 5 feet.  Obviously it depends on what kind of electronics
is at the end of the cable.  The cable is just a regular 50-wire ribbon.

	Why do we do this?  Well, we couldn't afford to buy a second
tape drive for the other system so we cross connect the drives when we
do backups.
