Mostly all videogames started out as a coin-up arcade version. The arcade's can be considered to be the mother of all videogames. That's why I always wanted to add some real arcade's to my collection. So these days my room is filled up with two arcade-cabinets. One of the cabinets has been altered to hold up more than one game(pcb) which can be selected from the outside. We are talking about standard cabinets.....so it ain't the real thing...but hey....it's running the real pcb's ;-)
