First Operating System: Windows 98
First Linux Distribution: Ubuntu Trusty
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!
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 Vista on my old family desktop.
First Linux distro, if it counts, was the Raspberry Pi OS
Ubuntu Feisty Fawn. 2007. I was looking for new and exotic ways to avoid writing papers.
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.
First OS: Win 95 (As a wee lad). First Linux: early lubuntu and backtrack that I used in college around 08-09.
