I have been around computers for my entire life. I remember playing DOOM across the home network; dialing into a bulletin board system on a 14.4 Kbit/s modem; helping my father install one of the first 1 gigabyte hard disks; and writing games in Excel's macro language. I recently came across two photos showing even earlier examples of the technology I had around me.
Here is a picture of my sister, father, and I using a cutting-edge (in 1987) Compaq 286. Obviously, my sister and I were already pair programming, 13 years before the advent of eXtreme Programming.
And here we are in 1988 playing a video game on our Commodore 64. Note the Atari joysticks.
What is your earliest memory involving computers?
