    How can I get my mac to boot to all 3? I know I need to get all 3 os's first. Do I need to create seperate partitions so they will all boot? How would I do that?

    Just make 3 different partitions. But the bigger question is WHY?

    yea you'd need to create 3 separate partitions, and install a separate OS on each. Disk Utility would create the partitions for you, and you'd want to install the oldest versions of the OS first i.e. install 10.1 first, then install 10.2, and then 10.3

    why on earth would you want to? If you're new to Mac, let me tell you this: MacOS is heavily backward compatible. With few exceptions, any application that runs on 10.1 will still run on 10.3.

    Haha, I want to do it because there are little differences in how to get around in them and I want to be able to help people that may have an older version.

    You cannot boot an OS that is older than the one that shipped with your computer. If you have an Intel-based Mac, you are limited to certain versions of MacOS X 10.4.
