I would like to run older versions of Mac OS X (Pre-10.4) on my Intel Mac either through an emulator, or possibly some dual-boot situation. Is this possible? And if so, how?

I actually asked a similar question here: http://lockergnome.net/questions/54814/running-a-classic-mac-environment

If you read the correct answer thoroughly it doesn't appear their is a way...

Oh really? Because I have a fully-operational version of Mac OS 9 running within my Mac OS X 10.6.4. I know that running anything before Mac OS X is possible, just not after. If you want, I can give you the link to download it, it's an emulator and it runs great. It's 530MB uncompressed.

You can run Mac System Software 1 to Mac OS 9.0.4 in an emulator, however there are no PPC emulators or virtual machines that support Mac OS 9.1.X and up running in Mac OS X. Mac OS 9.1.x added a new protected memory system / kernel that has not and never will be supported by Sheepshaver, and since the intel transition, there has been little need or effort for a PPC emulator.

The best bet is PearPC, which is a PPC emulator capable of running Mac OS X (extremely slow) on Windows and UNIX systems. Mac OS X, being a POSIX compliant platform, should be able to run PearPC via X11 if you compile the source code.

Cheaper than the OS? Old versions of OS X can be as cheap as $10 on eBay. Plus, why would i want a bigger, slower computer just to run an OS?

PearPC can run Mac OS X as a guest. It supports POSIX OSes with X11 compatibility as the host.

Mac OS X for PPC has been available this way inside Linux on x86 and PPC for years, all one needs to do is make minor changes and compile for an OS X host ;)
