9.15 OS9

OS9 Betriebssystem

OS-9 is a multi-tasking, multi-user operating system developed by Microware for computers using the Motorola 6809 and 68000 cpu's. I've used it on a Radio Shack/Tandy Color Computer and also own the Atari version.

I would love to see an OS-9 based personal computer running at 500 mhz in a windowing environment. It would runs circles around any Windows based computer. It still is called OS-9.

There were two ports to the ST I believe. One was done by Reccoware Systems in Germany (rebadged and sold in the UK by Cumana). The other was done by Microware, the company who created OS-9 (although this could also be a rebadged version of someone else's port - I just recall seeing it in their price list a long time ago).

Somebody must have been naive or arrogant to call a os OS. :-)

But they didn't, they called it OS-9 (which originally stood for "operating system for 6809" - it got ported to the 68000 and other processors later).

There was indeed, and there even used to be an OS9 website related to it. Can't remember where though.
