Quoted from aberdeentp:I just found this post, I have this topper, a friend found it in the depths of the warehouse of the Game Exchange in Denver, they had it for years but guess they never got a game to put it on. So he negotiated a price for me and it's on my Laser War. I doubt there is enough interest to warrant a reproduction but if anyone decides to I can try to help anyway I can. It does work, and does all kinds of tricks, I imagine it would be better in a darkened room.
Is it interactive with the game? What wire(s) connect to the game and where?
