(#ijtgw3a) @logout@i-logout.cz Windows can run on QEMU on Apple PowerPC machines, but I think you need a G5 Quad for it to be even remotely usable. Here’s Windows 7 on a dual PowerPC G5. I’ve seen QEMU running Windows on a G5 with GNU/Linux as the host OS as well.

Microsoft also had their Virtual PC software for PowerPC Macs.
