If I recall correctly, the actual floppy controller is on the Logic board. And it's one drive per Controller. hence the reason the dual-floppies have dual ports for floppy. The controllers only handle one device per connector. Sorry guys, it's not possible to put two drives on one cable. The only reason PCs can do it, is that the floppy drive itself has the controller on it. Also, the reason a mac can eject the floppy by itself, is because the computer has direct control over the floppy. It's also another reason floppies are faster read and write in a mac than a pc (they format faster, and they can access much faster than a pc can)
