I have one. I have two joypads, power supply and the computer itself. The top flap is present, but one of the hinges is broken. I may have some other wires for it. It has not been switched on for many years. I am not sure of the value of one of these. I know that having the flap is a big bonus and the joypads are rare. If somebody could give an honest value I will see if it is worth me selling it or keeping it as a nice ornament.
