A
I went to a small and poor elementary school. I remember the first time a computer showed up in class. It was 5th grade and the computer was an Apple. It was the only computer in my school. This was the 80s and it was a $2, 600 machine.
Before I discovered computers, I took typing class on old typewriters and I was the kid in class that repaired the typewriters. I remember spending hours trying to figure out what each typewriter needed to fix a stuck key. I was also the Audio/Visual geek (狂热的人). This meant I was the only one in the class who can thread (穿过) film onto the projector.
Anyway, when this Apple showed up, I immediately opened it. I had to see what was inside. This totally freaked out the teacher but it seemed clear I wasn't going to break it. I quickly learned how to get out of educational games and write things in BASIC. This was all in 5th grade.
My 5th grade teacher and I stayed in touch until her passing. I honestly don't know what I'd be doing if she hadn't done something extraordinary. She let my father and me take the Apple home. I'd spend the weekend programming, reading the massive notebooks. This was a $2, 000+ computer in the middle of the 80s—the pride of the school—and they let me take it home. A year later, I came home from school one day and the family car was gone and there was a Commodore 64 left in its place. My parents had sold the car and bought a Commodore.
Now, I think about this crazy journey. I am standing on the shoulders not only of computer science giants, but also heroes like my parents and my 5th grade teacher. Thanks Mrs. Hill, for introducing me to computers even though you were breaking rules. Thanks, Mom and Dad, for bringing a computer home even when there wasn't money for one.
