Amiflop drives the Amiga floppy controller, which is completely different from the PC-style floppy controller. Ataflop drives the Atari floppy controller, which seems to be a WD1772 and not related to PC-style floppy controllers neither. So none of them drive PC-style hardware, and both predate the generic readb() infrastructure.
