It would be much easier to swap displays from one 2400 to another instead of doing the processor swap. Swapping the G3 is an intense and challenging task, I have done it 3 times and I really would not want to do it again. The 2400 internals are in some ways more complicated than my 12" G4 internals. You could also try making a custom boot CD that includes the G3 upgrade extensions. Good luck. joe
