Only 2 ways to do it... either manually, placing all the sub folders in the correct runtime subfolders. Or.. Your powerbook should have Classic OS 9 installed unless you've trashed it or reformatted the drive. If you have it Mac installer is the answer it automatic and you can customize as well. Welcome to Macintosh I know it's quite different from The pc you had but once you get used to using it your gonna love it!
