	This being a DECsystem 5500 will be significant later...

	The tape system you refer is the TF857.  The "TF" part
	means it's a DSSI tape drive.  I suspect the "7" part
	has something to do with the loader.  It uses a cartridge
	which on the outside looks a lot like a CompacTape I and
	II (TK50 and TK70).  I suspect the media inside is a bit
	better than either.  It looks like a good tape system.

	That said; ULTRIX doesn't support it.  It would be an
	expensive exercise on your part to find out if lack of
	support means it's untested or doesn't work.

	Perhaps if there's a demand for it we'll make a SCSI
	version someday.  Let you're sale representives know.
