This is a new member of my Pippin collection: The Atmark Wireless Controller Set (BDE-82014 / PA-82014). It has the same functionality of the standard AppleJack controller, except that it is wireless. Three infrared LEDs send the signals to a receiver. The set is advertised as compatible with both Pippin Atmark and Macintosh computers. The latter require a P-ADB to ADB adapter and the AppleJack system extension (not included).
