- MSX Basic
- MSX DOS 1, 2 (and some variations)
- SymbOS (is there any source for this one, cannot find it)
- Uzix (is there any source for v2, cannot find it)
- Breeze
Any more? With sources? Any dev still going on or people moved to games only for MSX/Z80?
On MSX OS it kind of different than what we use these days... I guess. Things you start from MS(X)-DOS I would not call an OS unless they overwrite their 'loader' completely in memory and take over it's services. But Win3.1/95 was also considered an OS (not by me though) while it ran on DOS.
But the more the better, I'm esp searching for something with an actual source. I would really like to find the uzix 2 source as that seems to be very easy to understand, but the creator is no longer reachable (at least not that I can find).
@Buleste, you didn't read what I wrote. MS(X)-DOS are OSs, but stuff you run on top (Ease, HomeOffice) are not. That's what I said.
And you can argue if win3.1/95 are actually OSs:
"An operating system (OS) is a set of programs that manage computer hardware resources and provide common services for application software." (Wikipedia)
I'm not sure 3.1 did this without MS-DOS, so then MS-DOS would be the OS and 3.1 just a GUI, not an actual OS.
Anyway, I was not wanting to nitpick, let me put it somewhat clearer; looking for an OS that manages the hardware and exposes an API, so not something that runs ON TOP of MSX-DOS.
I agree with the Wiki quote. An OS is the service that runs the whole joint. The userinterface is actually a program using the Os services. But we can asume that most OS-es include a userinterface.
