Wasn't the TRS-80 the greatest though? I'll never forget being seven years old and getting one as a hand me down from somebody who thought it was worthless(and was pretty much right). Countless hours of playing outside lost in front of that puke green screen trying to decipher the garbage software loaded off cassettes, only to see "syntax error" over and over again. We sure have come a long way.

Amen, brother! I seem to remember being upset when a speaker magnet for my electronics project got a little too close to the cassette and erased a *lot* of coding for a RPG. That sucked.

I agree, we have come a long way.

You remember that weird plastic burning smell you'd get out of the TRS-80 after you ran it for a few hours? I miss that

Yes, I do remember it and not too fondly either . . . *G*

The TRS-80 model-1 where the plug for the power-port was exactly like the one for the cassette port?

. . .

Somehow, I did not get in trouble . . .

(Whups, "Mrs. Coe, are you still out there?" If so, this forum just turned into a Confessional...)

Wonder in design, eh? The ADAM received it's power from the printer, and the printer plugged into the wall. So you couldn't get away from the printer.

Wow!! Talk about a walk down memory lane...the good old days.

i dont know if you asking about pc's in general or os's that just run on x86 ?

here are some device specific ones:
open-moko
android
palm-os
mainframe-mvs
mainframe-cics
symbian-os
capcom cps-2
ms-dashboard (xbox)
...

im sure you can emulate some of these but not sure of there usefulness.

my college senior design project was creating a palm program using hotpaw basic to send data thru the serial port to a braille machine.

KERNAL on the Commodore Vic-20 and Commodore 64 was my first PC OS. I even had a book on how to program for it.

I see one missing from the wiki, I worked with AMOS, Alpha Micro OS. The Alpha Micro was a Unix like system that died in the 90's. Company I worked for just out of college used it for CAD, Computer Aided Dispatch for 911 centers (PSAP).
Since the Op wanted a funny story. Alpha Micro added a software disk cache to the later versions, it was called the SCSI dispatcher (remember everyone pronounces SCSI as scuzzi). So were sitting in the back of the center working in with one of the newer aplha's that been having a problem, senior tech is on the phone with Alpha telling them he thinks its a problem with the SCSI dispatcher and I'm snickering as the two 911 dispatchers keep turning around and giving him funny looks, he finally caught on that they were taking offense to the 'scuzzzi dispatchers'.

Should add my bit:

And lots of different linuxes.
There a few that have missed out have forgotten the names of them.

one thing I see left out completely was interactive BASIC with O/S commands built in like the 8bit computers of the 70s and 80s these computers had no real O/S at all
