Tales from the crypt: Our first computers
Computerworld editors share stories of their first PCs, from classics to clunkers.
By Computerworld staff
March 25, 2008 (Computerworld) Quick -- what was the first personal computer you ever owned? You don't have to think about it for even a second, do you? No matter how many machines you've had over the years, you always remember your first -- usually with great fondness.
In that spirit, we asked several Computerworld editors to share stories of their first PCs. While most of us joined the ranks of PC owners during the '80s, one editor didn't buy his first computer until 1995, and one "personal" computing tale dates back to 1970. Some of us were lucky enough to own some of history's great PCs, while others got stuck with turkeys.
We got a kick out of remembering the days of CP/M and DOS -- when programs ran off a cartridge or floppy disk, when a 6-MHz CPU was plenty fast, and when just owning a computer was the mark of a technology geek.
We invite you to reminisce along with us, then share your own tales in this article's comments area. We know you've got great stories to tell!
1982: Programming in BASIC, playing TI Invaders
My first home computer was a Texas Instruments 99/4A. We didn't have a monitor (we hooked it up to our television set) and there was no disk drive. Applications came on cartridges, and when I wrote my own programs in BASIC, I stored them on, yes, an audio cassette tape.
But it was a 16-bit system, which was fairly impressive for the time (I believe it was the first 16-bit home computer). One of the applications was rudimentary speech synthesis, which seemed exceedingly cool 25-plus years ago. Having unlimited access to my very own machine was quite a treat. Back in high school, we used terminals connected to a time-shared mainframe, and the school had to pay for computer time used. My computer classes were cautioned not to waste that expensive time playing games (a warning that let's just say wasn't entirely effective).
I could play chess against my very own computer as often as I wanted, as well as games like Munchman and TI Invaders (quite a step up from Pong).
We eventually bought an acoustic coupler for it so we could dial into local text-based bulletin boards run by hobbyists. I've been hooked on online information ever since.

My first computer was the ones we are still cerently using: Window XP. My mother bought the family computer in around 2001. It had a very small moniter, but with the standard black dell ball-mouse, keyboard, and harddriver. We still cerently have this computer in our new home, in my mothers office though she is normally the only person who uses it. i myself use my laptop that is about two years old. it has a wide screen and tree dvd players. My first computer was not an older one like the staff at acomputer world though some of the computers/ operating systems they mention i may have used in the past either in elementary school or at my aunts house.
