what was your first computer's operating system?

[TeePee4Prez]

DOS 5.0 or PCGEOS.  Yep that was 1992!  Got Prodigy in 1993 and I thought that was the best thing since sliced bread.  Got Windows 3.1 in 1994 and started to download porn that took 3 hours for a simple picture.  My friends thought it was better than PayPerView!

Windows 95, I think.

The first computer my parents had was a Timex-Sinclair purchased around 1983, so the operating system on it was probably Sinclair BASIC. They got rid of that computer in the early 1990s, several years before I was born. The earliest computer I remember them having was purchased in late 1994 and originally had Windows 3.1 on it, but was upgraded to Windows 95 a few months later. I remember using it to go on some kids themed websites in the late 1990s.

Family: MS DOS
Me: Windows 98

I used to love dicking around in DOS and QBASIC as a kid. We had computers in a few classrooms at my elementary school and during inside recesses I'd hope on and make programs that did useless things like draw circles randomly all over the screen. Kids back then thought computers were still a novelty for social misfits and I quickly gained a reputation as a huge nerd who must be like sooo smart. Good times.

Family: Some form of DOS, I think?  Something with a command line anyway.  That got replaced with one of the original iMacs.

Me: Windows XP

some version of IBM DOS in terms of my family's computer.   the first one that was my personal computer was Win 98.

The first OS I really became familiar with was my aunt's computer which ran Windows 95. As for my own computer, it was Windows XP.

My family's first computer was an Apple iic, so I guess the operating system was Applesoft DOS 3.3.  Actually, I loved that machine.  I had gotten a chance to play with Apple iis in 6th grade, but when the iic came out, it seemed much fancier and had lots more RAM.
