My first brush with my future was when I was about 5 at SRI. My father used to work at SRI, and sometimes I got to see some of the punch card machines the students and researchers were using. Huge metal things where manilla cards would go in one end, and come out in a plastic holder at the end. Sometimes my father would bring home a ream of computer cards, and I'd make houses out of them.
I went to computer camp for two years (4th grade and 6th grade), where I learned how to program on mainframes and Atari 8-bit systems (800XL... how I miss thee).
The first computer I actually outright owned would technically be an LED calculator, but to follow my own rules, the first "real computer" was a Timex Sinclair 1000. It was a small "all-in-one" black unit, ZX80 chip, about the sized of a hardcover book, that hooked up to your TV set for a monitor, and a cassette player for storage (which, when played on the stereo, went "BEEEEEEEEEEEEEEEEEEEEEEEEEEEEP BOOOOOOOOOOOOOOOOOP BEEEEEEEEEEEEEEEEEEEP BOOOOOOOOOOP..." like a modem on Quaaludes). I got it when I was 15. One of my high school friends, Nicole Peacock, gave it to me in a paper bag because he was sick of how it sucked compared to... hell, stevonwolf's systems (Steve, I hate to say it, but your mom set you up with teh tricked technology. Damn, you always had the latest and greatest computers/game systems, and Nicole, Fred Vogel, and I were sooo jealous, yet not jealous enough to avoid showing up at your house all the time). Anyway, Nicole's bitterness was my gain. I programmed my little box to insult people, draw cubes, and even did a cheesy 3-D simulation of going down a hallway.
