Writing SCSI 9-Track Mag Tapes from Windows/DOS

[Marc Verdiell]

Woot! I finally got my HP 7970E (yeah, a year in the making!), HP 88780, and
Overland Data OD3201 9-track tapes all working at the same time. One on
HP-IB, one on SCSI-1, and one on Parallel Port interface. Only my ever
finicky Qualstars got jealous and decided not to play ball. Here is a family

The DOS computer is a vintage Dolch PAC 65. 
Thanks for all here who helped with tips, documentation and software.
