Other OSes for Amiga?

[Dr_Righteous]

Aside from POSIX OSes, has anyone ever created an alternative OS for Amiga? Perhaps even going as far as to create their own KS ROMs? Just curious...

[MrZammler]

Check this one out:  pOS

I have an archive of it on my A3000, must be beta or something, but have never gone around playing with it.

I have a basic window manager that runs on an Amiga (uses the chipset directly), but I never got around to writing a kernel to run programs for it. (I wasn't intending to write an OS, just experiment my own WIMP system). So, effectively, I wrote 0.01% of an alternative OS ;-)

None apart pOS.. but someone could try to port FreeDOS, an msdos open source clone... even if it would be a bit pointless

Forgive my ignorance, but what does POSIX mean?

Oh, and I know you can run Debian on 68k, not that I've ever tried it...

I don't know exactly what POSIX stands for, but it generally is used in the context of "POSIX compatibility", programs that are POSIX compatible are basically "UNIX compatible".  A POSIX compatible OS is usually a derivative of UNIX.

I'm sure there's better explanations on the www :-)

POSIX on the Amiga Wiki :-)

Well MacOS upto v8.1 can run on Amigas using the 680x0 processor. All you need is a program to boot MacOS such as Fusion, Shapeshifter etc.

Other OSs include 68K Linux, BSD Unix etc

On older Amigas, its possible to run Atari's GEM OS
with some boot software.

I have the unoficial 68k linux cd but have never used it because it is to much messing around to install it. :-)

IA POSIX compatible OS is usually a derivative of UNIX.

Not quite.

POSIX is a programming standard which I think originated in Unix systems but is by no means Unix specific.  It's usually used becasue it's required in systems that the US government use.

Completely non-Unix OSs can also be POSIX compliant (to a greater or lesser degree).

e.g. Windows NT, BeOS, QNX.

I played around with my own ROMs in my A500.  Goal #1 was to turn the low-pass filter on and off to blink the power LED.   It never actually worked partly because I'm not very knowlegable on 68k asm or the Amiga architechture.  It's quite abit more complex than a microcontroller.  My expierment was far from being an OS.

Thus my choice in saying POSIX rather than spelling out BSD, Linux, Unix, QNX, etc...  :-D

pOS sounds like it would have been interesting... FreeDOS would make a cool port, just for S&G's. Hell, start with a CLI based OS and build from the ground up!  :-)

I remember seeing a version of OS/9 68K running on an A1000 one time as well as CP/M 68k.. I thought hmmm.. what a great sorta off topic response  :-D

What's nice is this wasn't through emulation. Also Atari ST emulators I have heard of, but I really mean the COMMAND LINE based CP/M 68k :-) Which neither were emulations. Now is someone ports SkyOS I might get really interested..

MacOS and GEM on the classic Amiga are ran via emulation. "boot software" implies some sort of bootloader.

Dr_Righteous asked if anyone had created an alternative OS for the Amiga. OS developement and emulation are quite different.
