I have my copy of AmigaOS4 for Classic PPC on the way. Unfortunately don't have the real hardware to use it yet (not sure if I'll ever be able to get a PPC for my A4000D) but with WinUAE supporting PPC, I figured why not, and to support them.
Would be nice if they released it for Amiga OS 3.x, sure looks like it could run on it.
Either way, cool, I'll probably have to back it.
