The 26-pin connector on these floppy drives are not easy to get hold of, I solved this by soldering a piece of floppy cable directly to the drive's controller. Adapters are also available but tend to be a bit expensive. Also, since these are made for PC's they would require a bit of modification anyway.

Laptop floppy drives have no separate power connector. Connect the 5V-pins to the 5V-pin (red wire) on the Falcon floppy connector.
The Ground pins on the laptop floppy drive can be connected to any of the odd pins on the Falcon floppy cable.
