PC Floppy Drive on X68000
The floppy drives in the X68000 are just regular PC drives with extra features. In fact, on the PRO they share the same part numbers with their PC counterparts (It's a TEAC drive). If you can live without soft-eject and computer-controlled blinking lights, you can easily connect a normal PC drive to the X68000. Simply follow this connection diagram, and you're done!
