My earliest memory is one of my neighbors had the Pong console with the dial controllers. Something like this: http://www.richardlagendijk.nl/foto/cip/computer_2000k_01.jpg
Playing Super Mario Bros 2 with friends. I had no idea what to do and got super excited to play that when you chose a character you're supposed to raise your hand by pressing up. Well, I didn't know that. They just said, okay raise your hand to pick your character.
I got the controller, and I raised my hand.

Some wire frame tank game on my dad's atari. Also remember playing mario brothers that was the mini pow game from Mario 3 at the level start.
I remember the atari died not too long after i first got it and my parents saw how much i enjoyed it so they got me an NES which kept me happy for a few years until one christmas when i was surprised with a Genesis.
