I'm playing with a WangDAT 1300 at the moment (image processing - need lotsa
storage space), currently driving it with some backup software that thinks
it's talking to a 1/2" tape drive and so sequential-reads everything - arrgh!

But even for the normal backups, I find them annoyingly slow, beating 150K/sec
on a good day.  But maybe when I get a driver written that knows what it's
talking to I'll do better... has anyone got any detailed info on the things?
I'm trying through various channels to find what progrmming manuals are
available, but a part number would be very useful in persuading people
that documentation must exist somewhere.

(I'm partially convinced the slowness is psychological, since the tape moves
so slowly as compared with QIC drives, say.)
