I remember the early Atari's playing pong and such, but what I remember most was playing Mine Storm and Pole Position on a Vectrex. That was cool back in the day. Screen, controler, and everything else you needed all in one box. Carry it over to a friends house and plug it into an outlet is all that was needed. Had too many computers to remember them all. I remember one that used cassette tapes, but cant recall the name.
