also, with any hope, you still have the "Pepsi" board in there. This is an interface that takes a cable from inside the Lisa (mates with the motherboard on the other end of the cage) to the card on the left hand side of the drive cage, from that card, another cable goes to the actual floppy drive.

This was used to convert from the Twiggy floppies to the 3.5" 400K Sony drives.

If you do wind up ordering an X/ProFile ask John Woodall if he has any 400K floppy drives to sell, he might.
