How to connect a slimline laptop floppydrive to Falcon

Laptop floppy drives are half the height of standard 3.5" drives. If you swap your Falcon's floppy drive for one of these there's 12.5mm that can be used for other things, like switches, SD/CF-readers, Gotek and other stuff that people usually massacre their case to fit.

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.
