It has a missing joystick knob and one joystick controller is broken. I would think that if they wanted such a premium price, it would be fully functional as well. I have no clue or idea what that thing is, but it does look interesting.
I don't even think it is compatible with a PC as it is. There are so many things about it that would make me look the other way.
With that said, I suppose it is a very rare thing. I've never seen anything like that before. It could be some sort of console combination controller and keyboard. It would make a distinct conversation piece, especially if you actually hooked it up to the computer and had all those gizmos functioning and doing something special.
