Dave and Busters uses the Sacoa system. google it and you should find a lot of stuff. Chuck E. Cheese's also used a similar system in a few locations. You basically need a computer network set up. Each of the games have a swiper and an x reader if you want to keep track of ticket/coin meters. They are actually easily to wire in. IIRC the swiper has its own power supply and is tapped into the machines 5v coin up line. Xreaders are spliced into the 12v output. Games go to hubs, hubs go back to a computer. and thats pretty much the jist of it. Changing out all the coin doors (you can eliminate tickets as well with these) and mounting the swipes is a huuuge pain in the butt. I personally do not think it is worth it, unless you are running a huuuuge operation. I think they even have wireless systems now, but I am not sure I would depend on that.
