First of all yes I'm 45.
So in your broad expanse of knowledge you are implying that as a kid it is impossible for me to learn and program computers?
For your information I and a couple of my friends were the "nerds" of our time. I started messing with computers in the age of Atari shortly after Pong. My friend's older brother had some little device that we would program really simple things on. I think it was a Texas Instruments thing. It wasn't mine else I could give you the exact name, manufacturer, model number because I rarely throw stuff away. I'd still have my Atari VCS if my brother hadn't sold it.
I programmed a Math game for my nephew when I was 14 or 15. It was like Pac-Man. The screen would display an equation and you would drive a car around the maze being chased by 4 ghosts. The correct answer was in one of the four corners. You'd advance a level reaching the correct answer. The chase algorithm was pretty simple. I had one randomly wander. One directly pursued. One would pursue and then change direction and the other would pursue, but at a slower pace. My nephew enjoyed it. He was 3 at the time and I'd say it helped his love for math ebcause he went UT-Austin for engineering.
When I as 13 or 14 I sent Atari a well drawn out plan for Star Wars game based on the vector graphics that they used for Asteroids. They replied stating the normal liability release stuff and about a year or so later they released exactly what I described. Now if I had been interested in legal matters as much as I was computers then I for sure had a basis for a suit.
So for the record my interests began with Pong which was around 1972. Yes I was 6 years old. Did I progam then? No, but my interest began at that time because I wanted to know how those things worked then during elementary I was more interested in Science and Math. Cleraly remember an article about "laser discs" and how they were the future. That the government was experimenting with them to store data. This was 1974 I believe. 3rd grade weekly reader that was passed out at school. Messed around with my friends TI device mid to late 70s. Then had my Atari VCS 1977. Had an Atari 400 then an Atari 800XL and my last Atari was the 130XE so yes during the 70s I was programming.
So yes from 1970 to 1979 I went from 4 to 13 and after the age of 6 was when my interest in computers and programming began and grew. So yes the 70s.
