Poll on OS you guys learned first.

I learned a while ago, CPM was my first microcomputer Operating system, and IBM/DOS was my first mainframe operating system.

I had had my first computer contact with some Macs. But I have really begun to learn with my first Windows 95 box.
It's the best OS to learn how to crash your pc with style... and what to do after the crash!

i used and programmed in the "Sinclair spectrum intepreter shell" and later on the Amiga o/s for the amiga 500/600/1200, then dos 5, then win95 etc etc

(remember your heritage) :P
Preep

I was introduced to computers on Apple IIs and Ataria 800s. My dad had the Ataria my best friends dad the apple. The first OS I learned was DOS 3 (??) the one prior to the Graphic shell. I read the entire DOS book and took notes. Its amazing how much I've built on that initial base.

Cheers,

Dos for me, And to this day, I still love it.

Well I beat you all....
Commodore VIC 20 Basic......
Then I started with DOS 2.2 (I think!) on a Sperry

Unless you count CW as an OS

Yes I am an old FART!

Apple IIe ProDOS BAYBEEE!!!

my first 2 systems was earlly 80's , but i remember nothing about it , but the word Apple and Commodore on each one - sence it was a game PC only :)

but the real one i did really enjoy playing with was :
american research corporation (ARC ) 286 machine running dos 5.somthing

Back to your main Q?
the first OS i knew all it's ins and outs was DOS 6.22
and what i'd like to know is Linux ins and outs.
conclusion: Windows golden age will be disapeared as soon as peeps get used to Linux or ( *nix ) OS.
that what i believe in :D

my first was m$ dos and then 2 win 3.11

first OS was DOS, i dont remember the version number.... then i went on the Win 3.1 wich was ****ing WIERD AS HELL!!!!!!!!! atleast at the time it was, and i remember not wanting to move to Win95 for some odd reason until a while passed and i finnaly did.

then it went so on and on and on until Win98se(thats the extent of my windows experience) and then came Linux and a little bit of BSD
