The first pins that I bought were the early ss's I played at Aladdin's Castle back in the late 70's.
Tri Zone, Lost World, Phoenix, Playboy. I still have 3 of them and sold the other to another Pinsider. I got hooked on TOM at the arcade as well and that was the first dmd machine I picked up. I still love the early ones but dont play them as much. I do however, make friends settle disputes by battling it out on one of them. Old school playground-style.
