Considering MorphOS for my iBook G4, BUT...

Well, like the A600, the iBook 12" has one advantage over its more powerful cousins: it's tiny.

MorphOS support for that model iBook is said to be planned for release 3.2. There might be a way to boot the ISO file from OpenFirmware, but I'm not sure. Can Macs boot from external CD drives? If you do get it booted and are planning usage beyond the demo, I join the recommendations of getting a new machine. Alternatively, I wonder it replacing the internal power supply would help - that would be cheaper.

As for MorphOS, I haven't seen any documention about what happens when it is installed onto incompatible hardware, such as an iBook.

Believe me, we've tried. When trying to boot, it'll hang at the OpenFirmware prompt and not go any further. "Unsupported" in this case doesn't mean "it might work, but you're on your own", it means "it won't work".
