A Backwards Mac
 

What program would I want to get to allow me to install Leopard on this machine? I don't want to try to make a modified disk if I can avoid it.

I think it ain't possible to install Leopard without having the G4 CPU Upgrade, for example the G3 lacks support for some stuff like AltiVec...

"Leopard can run on older hardware as long as they have a G4 upgrade installed running at the 867mhz or faster, have at least 9 GB free of hard drive space, 512 MB RAM and have a DVD drive. Leopard however will not run on the 900mhz iBook G3 models even though they exceed the minimum 867Mhz requirement. This is due to the lack of AltiVec in the G3 line of processors and the fact that most pre G4 and early G4 systems do not have video hardware capable of supporting Core Image, two technologies Leopard relies heavily upon among others. Leopard can be "hacked" (see below) to install on these G3 and pre 867mhz G4 machines but the system may behave erratically and many of the programs, features and functions may not work properly or at all." - Wikipedia

Well it seems that it is possible after all with a little hacking done, but i don't think it's worth the effort ( stability and performance....ugh ) Tiger is good enough ;)

Well, its back to the original problem. My system is not stable as it is running Tiger. I am getting Tiger, probably Tuesday, and if I can reinstall over (probably with a format) and get a stable HD, I'd be happy. Then there is the issue of what won't run at all....
