I was 7 years old and my father bought our first PC, something like a 286, 386 or possibly even a 486, don't remember... Anyway, the guy that was setting it up was a programmer and I watched him first set it up and then I watched him program something into the wee hours on our new PC, I've no idea what he was doing, but I watched him for hours, was dazzled by it as much as by the games he installed :)
