Hi, Is it possible to use a varient of UAE or what ever to run OS 4 on any PPC architecture?
UAE is 68k emulation, so there is no way it could run the PPC-based OS4.
There are many platforms that theoretically _could_ run OS4 (mainly PPC Macs), but you would need a legal copy of OS4 for that, which is only available bundled with the no-longer-available AmigaOnes. :crazy:
Emulation _is_ possible. Adam Kowalzcyk (ACK Software Controls) managed to boot OS4 on x86 using QEMU PPC.
