It's true they are not similar to Mac hardware (but I think old world Mac 
is closer to CHRP). However the Sam4x0ey are also not like CHRP or any 
standardised platform, they are similar to embedded PPC boards (I don't 
know about the Efika). So I don't think this is useful for Amiga like 
OSes. For NT for PPC we also have 40p (RS/6000) emulation in QEMU recently 
which may be closer to PREP/CHRP and maybe it could run NT for PPC (and 
other such OSes) with less changes.

For Amiga like OSes the Sam460EX is a good target because it can run both 
MorphOS and AmigaOS today (besides Linux). I have a somewhat working 
version in QEMU now but it still not working enough to run any of these 
OSes yet but I'll try to clean it up and merge back to QEMU (maybe in the 
next development cycle) so others can try to look at it too if I'll have 
time for that.

I'm not interested in Windows but OS/2 for PPC seemed interesting until 
I've read that even the final released version was very unfinished and 
lacking e.g. networking support. So maybe it's more useful to spend time 
on enabling some more useful OSes (which are not available in other 
already emulated versions) than these obscure ones. They seem to only be 
interesting for historic reasons for which is probably better to also get 
a real RS/6000 to run them. But of course everyone can have their own 
opinion on what's interesting to them.
