I would really like to find a manual or schematics to the SONY MPF42B-1 Floppy Drive. It appears to be nearly identical to it's sister drive the MPF42A SuperDrive found in Apple PowerPC's. This drive is a 4 speed floppy that was made specifically for some floppy disk duplicators. It uses a 20 pin ribbon cable - just like the apple drives. The picture below was stolen from eBay.
