Ah. I guess I read that wrong: 'I've never seen a Wacom product for a Mac that did not use ADB.' I see now that you mean that this model is the anomaly. Yeah...it's definitely a Mac model. The guy has all the original Mac drivers floppies, etc. But as you say, ADB is not readily apparent. I was thinking maybe it had a RS-232c to ADB cable or one that maybe went from 9-pin to 25-pin. When you say a DB9 to Mini DIN adapter, will I need another adapter to go from standard PC Mini DIN to Apple's ADB?
