I made this like 400 years ago, cant promise these drivers for networking will work on modern systems but the emulator and tutorials are all valid for the emulator. Use at your own risk! I suggest running this on Windows XP in a Virtual Machine. I drafted a tutorial on how to configure it from scratch so you can learn the process. You will also need to download an install ISO for mac OS X. PearPC should run 10.0 - 10.4 though 10.2 or 10.3 is best.
