Finally took the time to find out what on earth AROS was all about, basically to me it's just like MorphOS, WarpOS or OS4.x.
Maybe you should take the time to find out what WarpOS is also then :lol:
The point of AROS is to have an open source, portable AmigaOS clone that is "source compatible" with OS3.1. AROS running on m68k Amiga systems is supposed to be binary compatible with OS3.1. However, most of the effort till now has been on x86, since that's the most obvious system to work on, allthough thanks to people like MSchulz there's also AROS for PowerPC systems (SAMs), x86_64/AMD64 and ARM. There is also AROS for m68k since long (AfA), bits and pieces even found the way into OS3.9 (the oh so famous colourwheel, maybe more?), but the goal is to totally replace OS3.x on real m68k Amiga systems, just like the various MiNT incarnations replaced TOS on Atari.
On a side note, it would be interesting to know how far apart AROS on PowerPC is from MorphOS and OS4 in terms of binary compatibility.
