The first version of Windows I used was 3.0 in 1991. Prior to that, I'd never seen a Windows computer.
My first taste of a Microsoft computer language was on a Jaquard computer, and everything was controlled by MS-DOS. My first Windows OS was Win95, then WinME, then XP then 7. It took me a while to bother with a PC because I was an avid user of Atari 800 & TRS80 (aka Trash 80) & Apple 2e. I went to pcjs.org & ran the demo of Win1.1 -- VEDDY interesting!
Pretty much where I was going to go. I had exposure to Windows 1 and 2 but nobody really used it until version 3. It really wasn't good for much until then.
