    I'm on a PowerMac G4 (the old kind), and I still run OS9. I have two internal hard drives, one of which has the OS. I'm now looking to update, spec. to a Tiger (10.4.xx), as that seems to be the last OS version that works on my machine. But before I start hunting for a Tiger license, there are a few issues that I'd like to understand first:

    If I format one of the HDs with Tiger, and then star up with that, can I still access the files on the OS9 disc without trouble?

    If I start up on Tiger (HD1), can I still run OS9 programs on HD2, or do I have to move those to HD1 and run them in/via Classic?

    Do I need to delete OS9 from HD2, or can I keep it there without it causing any trouble?

    1. Yes you can!
    2. Neither. You have two ways of running those Mac OS 9 programs:
    a. Boot into Mac OS 9 then run them (best for programs incompatible with Classic)
    b. Run them directly from HD2 using the Classic environment in Tiger (best for programs compatible with Classic)
    3. Keep it - it'll make your life a lot easier running Classic programs.
