	The SCSI tape controllers work fine, ICD sells a SCSI tape
system.  The various floppy based tape interfaces (ie. QIC-40) don't
work.  The STs floppy interface just isn't clean enough to drive one
(several companies have tried it).

	The HP Nighthawk is not a SCSI drive, it is a custom version of
ST506 interface.  All signals and power are fed through the 40 pin
cable.  To use it with the ST you need a HP SCSI controller.

	Unfortunately several mail order companies are now selling
Nighthawks (for <$250) and are saying they are SCSI.  Lots of people
are buying the drives only to find they can't use them without buying a
HP controller card.
