What Brian said was true a few months ago, but not any more.

The newer Sun tape drives that go with the SPARCstation 1 and the other
new Sun products are not Qic24 60MB tape drives but Qic150 150MB tape drives
( However you can still use the old shoeboxes with the newer machines if
so desired ).  The list price for the Qic150 drive is $1,600.  I suspect
that with his discount, Dan was being offered one of the new drives.
The speed is roughly the same as the older drive ( 90 ips ) and the newer
drive offers higher density ( 10,000 bpi as opposed to 8,000 bpi ).
Rewind time is also roughly the same ( 1.5 min. ).

Not being able to add to a tar file can be overcome to some degree by
winding past the end-of-tape mark of the existing image and creating a
new tar image.
