My first pc was a turbo XT! And that button was always activated
MS-DOS was lightning fast to boot up. I had all the common CTRL-key commands memorized and it was like working an abacus in Word Perfect I think it was. So fast and easy. Then Windows & the mouse came out and it was all downhill from there. 286-AT, dual drives (still floppy then later the 3.5s). I can still hear the dot matrix zipping back and forth - did my own print ads on it then had the print shop make copies adding my own real photos and sometimes stick on letters.

Oh man, autoexec.bat . That's enough looking back then for me!

Oh no I'm wrong, first pc was the TRS-80 with cassette tapes.

Actually no, it was book on computers my Mom got me. In the back was cardboard pages with cutouts representing memory so you could set bits with punched out bit pieces. You could do the math exercises in the book. Wish I still had that book as a keepsake.
