TI-99/4A with expansion box and UCSD P-System

Another for Commodore 64 w/Basic and 6510 Machine Language (SYS 49152), though I guess you could count the Trash-80's we used in elementary school (though I didn't really use the OS on there)

Windows 3.1 in the early 90's for me.

I had the Sinclair, which came before that. You had to solder the thing together yourself and it didn't have even the 1k of memory the Timex Sinclair did. I believe the Timex ran on a z81 chip and the Sinclair ran on a z80. I also had to use a cassette player to "save" the programs. Also, depending how long the program was, the top lines would disappear because there wasn't enough memory to hold the whole lines of programing. It ran on basic. Now THAT was the wild west of the computer age. Every company was trying to dip its toe into the world of PCs and most slipped and drowned.

I think it was CPm on those.

I didn't have the expansion, but that was my first as well. I can't believe I thought cassette tape program storage was cool! LOL

Your poll should have included Apple -- which is really not the same as a MAC OS - because I used an apple before the TRS 80

BASIC

IBM System/360

Ohio Scientific and then CP/M

Basic. Just like many of the early machines.
Commodore and Apple (Integer Basic) also. But you could use 6502 assembler with either. Apple also used pascal later on.

I used all of them for home use. For work, IBM 360 assembler, but originally worked on one with IBM 1401 (punch cards) at UF.

Wow - I had forgotten the Tandy I learned Basic on. One had cassette back up. When it worked... When we finished we could play a text based first person "shooter" game that was all on cassette. Sometimes, when you moved to a new room, it told you to insert a certain number tape. We were so cool in that storage closet with 4 Tandy computers!!

I don't know what it was called, but it was on a deck of cards that you put ahead of the cards you had punched your program into.

DEC PDP11 with unknown OS (I was in high school...) and Commodore

PC/GEOS Geoworks Ensamble was the first GUI I got my hands on. Never could get OS2WARP to run on my PC.

Ditto. so Pre-Mac OS.

Commodore BASIC 2.0, on a VIC-20.

EXEC 8 on a Univac 1100/80. The first PC OS I used was CP/M on a Z80.

YES, IMSAI 8080 ... I do miss those Front Panel rocker switches.
But actually, my first was a MITS Altair 880B (8080 processor versus the Z80)

Apple DOS, Then ProDOS and finally MS DOS and all of it's following OS's and user shells minus Vista. Properly speaking DOS was the apple II operating system and MS DOS and IBM DOS were the "Clone" & IBM PC OS's respectively.

IBM only went to Bill because CPM wanted too much! Had they seen the future a little more clearly we would have all been running CPM v 12 ... Wordstar ... Visicalc .... Ha Ha Ha

CPM on a "portable" Kaypro that weighed about 100 pounds and had an orange screen.

Since the Commodore didn't have an OS as such I'll have to say Commodore BASIC which came with the computer.

Basic on a Commodore PET 4016 with an external a cassette tape to "load" programs from.

Windows 3.1 was NOT an Operating system. COME ON!

My first 'language' was LOGO on a TRS-80

OS/2 was the first I used.

I'll nerd in on this...

I think it was KWICOS using a casette tape on a Trash80 Model 1 -- does that even count as an OS?

CP/M - 8 (On a Kaypro 10, with a whomping 10MB hard drive & 64 KB RAM) That was living! 7" monochrome screen, a transportable computer that weighed more than a SmartCar. And I STILL GOT IT!!!!

The first OS didn't even have a name. It was a proprietary system(SACCS 465L) for the military back in the mid 60s. The system would have filled a large house. There was also an IBM 1401 attached to it as an input/output device.

SCOPE (Supervisory Control Of Program Execution) on a CDC 6500. Punched card input mostly, with Teletype(tm) time-sharing access for the privileged few.

HDOS on the Heathkit H8 computer.

Ahhh! Punch cards and punched paper tape on a Teletype. But first you had to hand input through switches the octal code to read in the boot loader from the card reader or the Teletype. BIOS? We were the BIOS!

Sinclair BASIC running on a ZX-81.

I started with a Tandy 1000 SL 80/88 and Basic. Then advanced to DOS 2.2 when I got a Hard Card ( Old School harddrive on an expansion card) and finally Windows 3.1. WOOT !!!! I was a rockin Geek.

Edusystem20 (paper tape) on a DEC PDP8/e. 8K core-stack ram and 3 teletypes.
