I have spent a bit of time trying to get OS4 loading under PearPC and Qemu. I didn't get very far with either. In order to use Moana on something other than a MacMini 1.5GHz I think we will need the source code.
I think the best way to get OS4 emulation would be to add PPC support to UAE. This would give UAE the ability to emulate an A1200/4000 with a PPC card, and hence boot the OS4 Classic which is available to buy.
This could be done on any platform with PPC emulation code. A modern PC/Mac should be able to easily out perform a 603e under emulation. On a real PPC machine, it could use the real processor and potentially be faster than any of the official hard ware.
PPC emulation code is already available in the Open Source community, so it would just be a case of integrating it into UAE in such a way as to accurately emulate a PPC card. A job for the UAE developers I think.
