Aw, man...when I saw the pictures I remembered that I used to play that thing for hours. Atari had some great games for those of us in the infancy of video games. It was like a new magical door opening that challenged our minds as well as motor skills. I still have an original Nintendo and an original Sega system. Don't know what happened to my Atari 2600 over the years.
I have my 2600 in a closet somewhere. I literally played it till I wore out the joysticks. I remember "rolling over" Missile Command (rolling the score counter past 999,999 to zero.)
