A small card with a 65c02, IWM or SWIM, ROM, RAM and a PIA/VIA type chip would do it. 25 pins to the PC parallel port, 19 to the Apple disk drives. Probably a plug pack power supply would not be enough as you really need +/-12 and +5 volt supplies to work with all Apple 5.25" drives. -- David Wilson School of IT & CS, Uni of Wollongong, Australia
