Speaking of these, does anyone recall the AtheneOS distribution/OS. There’s an archive.org copy of the desktop environment version of it, but I recall there was a really fast version with only 2D graphics and it was a full distribution.

Can anyone validate whether this is real? I tried contacting the guy who wrote it but the Companies House address for his company (Rocklyte) bounced the letter.

Syllabe OS?

Huh, SyllableOS might well be it. I thought for sure it was a different version of Athene that I was running but now looking at the screenshots they have a weird familiarity to them so maybe it was just around the same time that I tried both and the memory of two decades has blurred. Thank you!

It mentions preemptive multitasking as one of its features. Are there any operating systems that still use cooperative multitasking?

RISC OS uses cooperative multitasking: http://www.riscos.info/index.php/Preemptive_multitasking

There is Wirth and Gutknecht's Oberon System. It's still available but is older than Visopsys -- it was created around 1990, then updated in 2013. I think it's now considered an historical artifact.

Many RTOS support it, eg FreeRTOS’s co-routines: https://www.freertos.org/Documentation/02-Kernel/02-Kernel-f...

I think it's worth mentioning on a hobby OS, just because it's a decent bit more work to do preemptive multitasking. It's a badge of honor to have successfully implemented it.

Took me a while to realize it's not a linux distro. Incredible!

It’s amazing how one person kept this project alive since 1997, that’s real passion and love for coding!
