the 40M qic-40 drive is *completely* different, which is not to say you
couldn't write a driver for it using the controller card.
hardware might also not be a big problem, but the drive was meant to plug into
the floppy-drive ribbon cable, not the controller's db-37.

my goal is to make it run off the *internal* controller...
