 Note : The connector on a floppy drive consists of 34 conductors. Both control and data use this same cable. Most cables have a twist that interchanges pins 10 through 16 at the end of the cable (on 1). Most floppy connectors have a "key" between pins & 6, and 3 & 5, to prevent the cable from being reversed. At the other end, the dual row connector that attaches to the controller card will usually have a set of ridges that coincide with cutouts in the controller card's connector. Note that old style floppy-only controllers used a card-edge connector just like that of the drive.
