I just bought a black 4 switch 2600 at Goodwill. It works, but strange things will be missing from the games. Say, if you plug in Pacman the whole game will work like normal, but Pacman himself will be missing. Something is missing from every game. I think this means that the machine is dirty, but how do I clean it? No Q-tip will fit in that tiny slot. I hope this question has not been asked before. I searched the sight for a similar problem, but could not find one.
Thanx, crazylegs
