I first used a computer directly in 1977. I accessed it via one of those scary modems that you had to actually plug in - it was a mainframe running Colossal Adventure and a Star Trek game where you had to kill Klingons which I had to use a terminal to access.
Before that, I used to play with punch cards that my dad brought home from work.
Not long after that, I got a BBC B and started to write code of my own (I'd already played around with a Research Machine 380Z for a while. My mother taught computer science and brought it home at weekend while I was still at primary school. It had a great program on it for learning Finnish (still remember some of it).
I wrote a decent adventure game based on a 4 by 4 grid at the age of 9. When I was 9, in 1977, Mr Blacklight wasn't even a twinkle in his mummy's and daddy's eyes.
I would like him to either say something interesting or useful, or alternatively fuck off.
I find his assumption that mothers don't know anything about computers annoying, prejudiced and weird. Also, you know, blacklight, maybe it's just YOUR mum that's a bit ignorant of computers? The rest of us are doing just fine.
