Computers reach one billion mark. I can't really remember what my first computer was, I was a kid... but I've been using computers since I can remember, since my dad's always used computers for work. I remember the before-Windows days, with only DOS around, and this DOS text editor which was red and blue and white, which my mom used to type up school stuff and I used occasionally to type up stories and such. (But I didn't like it how it automatically justified the text, so once, when I had to type up something for school and then print it, after typing it up I went and painstakingly removed each extra space. Then mom came downstairs to see what was taking me so long - this was 11pm, by the way, and I was maybe 7 or 8 years old - and she found what I'd done and insisted on replacing all the spaces I'd taken out, one by one. ^^;) And my dad had made a disk with games for me and my brother, it was one of them large floppies, and we put it into the drive and go to the B:/ drive in DOS and run autoexec and the program would give us a list of the games, and we'd pick which to play. And there was a labyrinth game, a railroad simulator, a qbert clone, a game called "Gap" which consisted of running around the edges of squares trying to change the color of them all without getting caught by the enemies, and you could press the spacebar and leave a gap behind you in which the enemies would get caught. And then there was a very crude banned editor, and me and my brother would make lots of banners and then print them out (on our printer with the continuous feed paper) and dad would get angry because we used up all the paper. Then we got Windows 3.1, and I don't remember much of that. Then we got Windows95 briefly, but dad couldn't figure out how it worked, until I found out how to activate the Start menu (from looking in the manual), but he didn't like it anyway so we went back to 3.1.
And I could sit here all day reminiscing about old computers and the stuff we used to do, but I suppose it'd get boring... ^^;
