Atari 2600 in 1980? Try 1978... Bobby Evans...Rahway's Roosevelt Elementary School. I used to go over his house after school, and my mom would be all worried. This kid had every single Atari game, and he was actually bored with the system. I was SOOOO jealous. I played Space Invaders for hours. I also played Tank with Punk Princess' older brothers. I loved the planes...
Finally, in 1980, my parents broke down and bought one (for $198 or something ridiculous like that). We had PacMan, Pitfall, and Pinball. I was so hooked. That's when Atari started doing poorly and you could pick up their games for $10-$15 bucks instead of $29. (I can't understand you X-Box nuts out there paying $49 for video games...sheesh!)
I had friends who owned colleco-vision. One actually had the colleco Adam computer/video game. We used it for a Science Fair project in 1983.
Other than my PC, my only other video game system was my Commodore 64. I used to belong to some Bulletin Boards (that's pre-Internet, for you youngin's out there), and I got all kinds of hacked...ehem, I mean, free software...ehem, I mean, evaluation copies of software to play with and write reviews for. I still have all the floppies, although I don't know if they still work after all these years. (1984 to 2002???)
