Put me down for PC/GEOS as well. Even though I owned a Commodore 64 before, GEOS is the first OS I recognized and used as such.

At the time, it was marketed as the OS that Windows should have been. I must admit, I liked it a lot better than Win3.1.

DEC VAX/VMS

Atari 800XL OS (programming done via BASIC).

1 week to copy the program from the magazine, 3 weeks to troubleshoot (find the missing semi-colon!) and 1 hour to get bored with it and move on to the next project. Good Times!

This was in 1977 or 78. The first computer I ever used had a CPU unit the size of a small suitcase. The green CRT/keyboard/casette unit (yes, casette) sat on the desk. I don't know what the OS was. May have been CPM?

Whatever OS was in the Apple IIe

Coleco Adam - EOS or CP/M. Don't recall - was in the 2nd grade.

My first computer was a Tandy TRS-80 CoCo II so what ever the OS was on that computer.

I don't recall if it was some form of licensed DOS or an OS that was unique to the CoCo II.

Following the TRS-80 was a Mac SE/30.

My Elementary school had a lab of hand me down Apple II's. Thats what I started to learn on then my Father purchased our first family computer an Packard Bell with Dos which we later upgraded to Windows 3.1... ooooo ahhhhhh.

Oh, was that the one where you loaded the OS in one drive and the program in the other? We used to just keep the OS in the drive, and then we replaced it with a hard-drive.
Now I'm feeling nostalgic...

I started with a TRS80, but it didn't really have an OS. Then upgraded to a Commodore 64. Then came the Amiga. Talk about revolutionary!

GEM/3 Plus!

CP/M and an Osbourne II.

Commodore64 Basic.

APPLE, green screen with tape. BASIC

MVS FTW.

Tandy TRS-80 running Basic

RT-11 on a DEC PDP-11. Amazing how similar DOS is to it.

Dos with PC-Shell!

cp/m

Apple DOS on my ][+

My first computer was a Tandy Color Computer 3 with Tandy BASIC and some kind of DOS variant that came with the optional disk drive I got like a year later.

It was a TRS-80 based machine. IF you've used an Apple II, or a Commodore 64, it was sort of along those lines. Lesser known contemporary to those machines.

I was too young to really understand it for the first year or so, but I grew into it, and learned to love that machine. Entering programs by hand and learning what they did, and learning how they worked by modifying them, then writing my own... it was a fantastic learning experience.

TRSDOS 6.0 on the good 'ole TRS-80 Model 4 (with two floppy drives and a 300bps modem!)

ProDOS on an Apple IIe

What did they run on Honeywell mainframes back in the 70's? (Talked to it over a 110bps acoustic coupler modem attached to a Teletype.) It was built on top of BASIC, just like many of the others, like the HP-2116C in our high school. Add in DEC RSX-11M on a PDP-11 at a summer job & then TOPS-20, AppleDOS, PC-DOS, XENIX, 4.1BSD Unix, and more in college.

Windows 97 ... I think.
