This is a relatively old and interesting looking model of a circuit bent Casio SK-1. The auction description mentions it being purchased two years ago, however the exact bend date is unknown. Not a very typical mod because I hardly ever see the numerical keypad installed on the SK-1s, usually patch bay and or toggles. This also features a joystick connecting to a DB-9 port on the front, my guess an off brand Atari spray painted. Its a shame that the person broke it during the move, or so it says. Never to less it would be interesting to see what this sells for.
