Hmmm, does this mean, for example, that an Everex EV-36 controller can be
used with an Archive FT60 tape drive, since Archive describes the interface
used for this drive as a QIC-36 interface? And is it also true that the
Everex EV-02 controller will work with any drive that uses the QIC-02
interface, like the Archive VP series, or a similar Bell Tech drive?
More generally, how interchangeable are various vendor's streamer controllers
and drives? Is it possible to write software that will work with many
different controllers/drives?
