MS-DOS 5.0

First Operating System: Windows 98

First Linux Distribution: Ubuntu Trusty

Windows 95

Windows 95 and Macintosh LC, elementary school computer lab stuff. My grandpa had a Windows 3.1 IBM PS/2. Those were all pretty old and practically obsolete computers when I used those, 98SE was out and ME was right around the corner.

My very first Linux distribution experience was Mandrake Linux I believe version 9 or something like that. Didn't last that long though, I revisited Linux later with Ubuntu 7.04 which is when I actually switched to Linux full time.

ArchLinux since 2011. Still running that install to this day!

Desktop: DOS

Mobile: Android 2.3

I cant help but feel this is some sort of password reset question farming...

Anyway,

ZX BASIC SUSE Linux 6.1

DOS/Win3.1 I was pretty young. It was far back enough that it was still common to find Apple II's in my grade-school classrooms off to the side for when we had downtime. I regret that I was just a little too young to experience the Commodore 64 craze.

Windows 3.11

Windows Vista on my old family desktop.

First Linux distro, if it counts, was the Raspberry Pi OS

PC-DOS on an IBM 5150 (iirc).

If you could call it an OS, ZX spectrum basic was my first. My first Linux was Slackware 6 or 7 installed from a string of floppies. Good times.

DOS -> win95 -> win98 -> debian (and i'm still here 24 years later...)

Ubuntu Feisty Fawn. 2007. I was looking for new and exotic ways to avoid writing papers.

Windows Vista 👶

First OS: Win 95 (As a wee lad). First Linux: early lubuntu and backtrack that I used in college around 08-09.
