Oh, well, since you mentioned Atari... I still have my Atari 2600VCS lying around (it was still in working condition a few years ago when I tried it... maybe I should connect it again and take some video), but years before that, my uncle bought one of these in the early 70s:

It had several variations of pong-style games, and we played it on my uncle's B&W TV... so that was the first video game I played.
Several years later, after it broke and couldn't be repaired, he gave it to me and I took it apart (I'm an electronics engineer now, so I could use the various pieces in other projects, and apparently the last technician who tried to look at it took the ROM, so it was "brainless" by then). I still have it lying around (well , the casing, I mean, as the various electronics components are in my parts shelf), I should maybe take a picture some day...
