Amiga OS 3.9 already runs everywhere. So?
It only is limited to past and requires JIT for productive use.
(running AOS3.9 on emulator on x86 is cost efficient way to use 68k Amiga on high res display, on laptop and with some 1Ghz 68060, other than that, not interested. + MorphOS on PowerBook already covers my mobile 68k/AmigaOS needs. (and I also have AOS4 system))
