Emulate PowerPC on an x86 machine. If you're brave and have the time, run OS X under Windows. PearPC is an architecture-independent PowerPC platform emulator capable of running most PowerPC operating systems. The following operating systems were tested and run (to some extent) in PearPC (ie. as clients): Mac OS X 10.3: Runs well with some caveats. Mandrake Linux 9.1 for PPC installer: Runs well. Mandrake Linux 9.1 for PPC after installation: Hard to boot. Runs very well afterwards. Darwin for PPC: Runs well. OpenBSD for PPC: Crashes while booting (accesses PCI in an unsupported way). NetBSD for PPC: Crashes while booting. AIX for PPC: Some people ask about that.....(free).....
