Well, the Pegasos2 is a cool monster!
I have MorphOS, Debian,Suse,Gentoo,Crux,Mandrake, YellowDog,
MacOS9,Jaguar,Panther(via mol) running on it!
For Amiga-ECS/AGA-games there is a mos-version of the newest linux-uae from evilrich...
MOS is very compatible to classic AmigaWB soft (f.e. I made the cd32-444
on it...). Very cool system in my eyes...
