    Ouch.... floppy drives are not IDE interface -- they are the 34 pin
Shugart connection that all 5 1/4" and 3 1/2" drives use. As I recall,
the IDE interface is 40 pins....

    Having hooked up a QIC-40 drive a few weeks ago, you just hook the
new cable into the controller and tape drive, and the old cable that
formerly pluged into the controller plugs into a special socket on the
new cable provided with the tape drive. Somehow, the floppies are
turned off and the tape drive is driven by the floppy controller.
