Your first operating system?

What was the first operating system you ever used?

The very first one for me was the BASIC OS on a Spectrum 48k. The dizzy series of games was so much fun!

On a PC, I think Dos 3.22 came with my first computer (an Olivetti 8086). I remember upgrading to 5.0 and 6.22 at a later date on the same PC.

First machine was a Speccy 48k! First PC was an Amstrad 1512!

But, I was using the original IBM PC at work which ran on DOS 1.0! Graphics and a clock were extras!

First OS for me was BASIC. My first home computer was the Commodore Vic20

Erm, BASIC is a programming language, not an Operating System!

Windows 3.11 and DOS 6.2 (something like that).

Good times.

My first PC was an IBM PC1, 64k, Dos1.0 2-1sided 51/4 floppies.
Before that was IBM 1401, 1410, sys360, sys3, sys34, sys38.
I'm OLD 8>)

Oh man, I feel humiliated. Here it goes, *gulp* Windows... X... P...
Although it's kind-of funny, at school, all of the computers use Windows 2000 and here at home I really only use W7. I don't know why thats "kind-of funny" but oy vey (no, I'm not Jewish, I'm just in the habit of saying that).

We've all get to start somewhere It just makes me feel old

I tried a spectrum emulator (which works online) to play some of the old games that I've missed:

It was 1982 and I think it was DOS 1.0

I started on a spectrum tape driven software good old daze
