"How does somebody know what they want if they've never even seen it?" POWERFUL!!!
It brought back memories. I remember in 1981, I was a teenager waiting for my mother at a doctor's office. The doctor gestured to some magazines, saying "there are some computer magazines there."
Why did he think I'd be interested in computer magazines? Did he think I was a nerd? Actually, I was a nerd, and I knew I ought to be interested in computers, for nerdness' sake, but I really wasn't. I picked up one of the magazines (probably BYTE) to see what was in it. It did nothing for me.
Fast forward a few months and I'm sitting by my father in a hospital room. I think he had some minor burns from a premature detonation of a trash bag full of acetylene. Anyway, he had brought with him a new toy: An actual computer. It was a Radio Shack PC-1. PC stood for Pocket computer. It had almost a kilobyte of RAM, and ran a small version of BASIC.
After playing with it for an hour or so with him, I was completely hooked. He wouldn't let me take it with me, but he let me borrow the instruction manual, which I devoured. Soon I was reading BYTE cover to cover, including (maybe especially) the plentiful ads. I drooled over every computer I saw, and within a year, I had one of my own. It was a Commodore64, so new that the "computer store" was in the back of an industrial park.
I now have in my possession my first computer, that PC-1, which my father gave me several years ago before he died.
