Early '80s. My mom worked at a bowling alley, and I'd get free credits in the arcade from the people who worked there.
Donkey Kong, Pac-Man, Zaxxon, Bag Man were favorites.
We got an Atari 2600 later. Our neighbors had a Colecovision. Even when I was a kid, I'd drool over the better graphics on Coleco and in the arcades. :)
