Just OS X (mostly) and Windows (when I have to) I thought, but on seeing what others have posted, I realised I have used a few more.

In labs at university in the mid '80s:

Mac System 1 (and maybe 2,3,4….. dunno really)
PC DOS / MS DOS (not sure which)

After a hiatus of about a decade till now on occasion, on various computers, none owned by me:

Windows 95
Windows 98
Windows NT
Windows XP
Windows 7
Windows 10

On the first computer I owned, the original 2005 Mac Mini:

OS X 10.4 Tiger

On the 2009 Mac Mini I own and use for 99% of my IT needs

OS X 10.5 Leopard
OS X 10.6 Snow Leopard
OS X 10.8 Mountain Lion…… which I am using now.

I don't have a smart-phone or tablet, and am unlikely to get one. In my limited experience the screen is too small for my eyes and too fiddly for my fingers.

when I was in school I ran statistical analyses on those insane Friden calculators.

therefore... also used slide rules throughout the 60s, early 70s.

Texas Instruments calculators of various kinds.

whatever DEC’s PDP minis ran back in the 70s, the apps were coded in octal
VM/CMS on 370 mainframes

Novell server protocols
A/UX
AIX on Risc hardware

MS DOS no clue the numbers, from the 80s on Compaqs and Toshiba laptops
MS Windows (3.1 then nothing except 7 briefly via bootcamp
Macintosh System Software 0.1 (Mac512k) basically no looking back after that.
Apple OS - Sys 7, 9 not sure I ever used 8
Palm OS on some PDAs, using the device w/ a Ti book that ran sys 7.x
OS X everything, skipped Yosemite, looking forward to Sierra but not early on
iOS - upgrades are a pain if you have a bunch of different device types.

favorite toy is a solar powered glass Panasonic basic calculator, it's just cool.
 
PC stuff:

- Most versions of MS-DOS
- Windows 3.x (can't remember the version)
- Windows 95
- Windows 98
- Windows 2000
- Windows XP
- Windows 7

- BeOS 5.0 Professional Edition
- BeOS 5.1 (aka dan0)
- OS/2 Warp 3.x
- OS/2 Warp 4.0
- OS/2 Warp 4.5 (eBusiness Server)

- Mandrake Linux
- Redhat Linux (this was back when they sold boxed copies in Staples)
- QNX 6.x (the desktop-ish version with the SDK tools built-in)
- Gentoo Linux (was around 2003-2006)
- FreeBSD (was around v7)
- OpenBSD (~3.x)

Other stuff:
- HP/UX (HP K570 mainframe)
- Omron UniOS (Luna 88k2)
- HeliOS (Transputer boards running in an old ISA based DOS system)
- Symbolics OpenGenera (MacIvory III board set in an old nubus Mac)

That "sleep" would be death, and thanks, but I shall pass :p

Hah! Still it's so fantastic that our brainOS doesn't have to be plugged in either all the time or else every ten hours just to survive. Who'd a thunk you could get an OS to run on bacon and eggs.. or just coffee.

As far as OS designed by people for machines, i have used laptops w/ systems capable of sleep for so long now that I can barely fathom being tethered to the wall. So strange when I think back on getting my place in the boondocks rewired... spending two days trying to figure where to put outlets in each room and thinking well but what if i wanted to use a computer in here, what then? What about an external monitor in the library?? I will never forget the day six or seven years later when I took a Powerbook 170 up in the back meadow on a lunch break... the active matrix display made it fully usable out there. Made me realize that a 200amp panel was past overkill :D

From System 7 till the present OS X, it's the Mac environment that's been great.
Linux - Unix have been another mainstay.
DOS - Windows et al have paid the bills.
Open Moko was a bit odd.
Androids been great.
iOS... meh.

This thread reminds me of the massive amount of time and money I've spent... :D

OP, realise this: you've given ultra nerds a platform where they can boast about how many OS' they've used in their lives (even if "used" is mis-interpreted and then exploited to mean that they turned on the machine and shut it down again, they'll happily leave that detail out, leaving you with the illusion that they're very well seasoned "IT professionals", and likely are anything BUT.)

I've BOOTED many, MANY OS', but used around 3-4 full time.

A can of boring, silly worms, you have opened.


PS: Pedantic point - why the exclamation mark in thread title? Redundant.

Quite the pedant, eh, but what's the point?!

Oh, and in addition to my post above, stashed away somewhere, I still have the coding sheet and punch cards made for me to run an analysis of variance on a trial I did back in the 1975. It was done on an IBM mainframe; I know not what operating system. From my point of view, as with OS X, it just got the job done.

Gee no one said anything about including copies of official certs :eek: we had to boot the OS we listed...

The exclamation point was code aimed at geezers born before Algore invented his story about the net.

Anyway this is a pretty good thread. Not every day @maxsix and I end up on the same page, for one thing.

You're 41 years old when you were young how many OS's were out there, then again how many were there when you were in college in say '92 now ad 10-20 years on your life and think about how many more there were.

Even in your late 30's or early 40's it wouldn't be at all hard to be proficient in 4 or 5 OS's and if your older likely double that number.

When I was a kid we had a commodore in the living room, a II, IIe, IIc, then a Mac in the Office. I took a programing class in HS that was a Tandy running DOS and brought a PowerBook with me to college. At college we had a labs that ran BeOS, Windows, OS/2, and System 7 and my truly nerdy roommate ran Linux on .x kernel.

Open Moko! It interested me but I recall shrinking at the cost of the hardware.

given ultra nerds a platform

– and hurrah for thatand before operating system software – and before the word nerd – there were systems such as this –

attachment.php


– and yes, I did use that mechanical system. Held it in my hands, it was enthralling and I get goose pimples just thinking about it.

Enough about people's ultra-nerdiness, back to operating system software

Also used a taped based HP OS in the early 80's and dabbled with various Unix & Linux OS in the late 90's but can't remember which versions.
I was wondering if anyone was going to date back to Windows NT 3.5 with me, I remember when NT 4.0 with terminal services came out as the platform for Citrix, ahh the good old days. I currently work mostly in Server 2012 these days, but I do miss the days when MS made servers with an actual desktop. :D
 
I spent four years working extensively on an OpenVMS cluster.... bet that makes me one of very few! Any other DCL coders out there?

Otherwise, just a bunch of linux flavors, a bunch of OSX versions / iOS, bunch of windows versions and windows server, the TI os... can't think of any others.

- iOS, every version.
- Macintosh, OS8, OS9, that one way way back on the original Performa, 10.x-10.10 (except Lion).
- Windows: 95, 98, 98SE, ME, 2000, NT, XP, XP2, XP3, Vista, 7, 8, 10.
- Windows Phone, first one. I liked it quite a bit actually.
- Android Ding Dong Head, DingleBerry (...whatever they're called. Version 1 and then version 3 I think they were), and the last one, Tic Tac or Mounds or whatever it was. Hated every single version.
- Watch OS (the first Watch)
- That Verizon OS they put on the MotoRazr, if that counts.
- Windows Mobile that used to be on those PocketPCs.
- PalmOS where you had a cheesy stylus and had a special way of writing.
- An assortment of Linux things that were hard to install, hard to use, and forgettable.

...and that's it. My favorite was Snow Leopard. Nary a problem, ever, the whole time I used it.
