You are bidding on a Casio "Hoop Commander" JD-8000-w Pocket Computer.  It is basketball-themed and the packaging features David Robinson.  Features messaging capabilities, a phone directory, a calendar/schedule, a calculator, a clock/alarm and a basketball "Shoot and Jam" game.  Lower right of packaging has a tear in it (see photo).  Requires two AAA batteries and one watch battery (see photos), which are not included.

Sold as is.  Uncertain if it works and unfortunately, I'm unqualified to repair if it doesn't.
Thanks for taking a look and please let me know if you have any questions.
