According to Apple's website, Panther can run on the original iBook and iMac. http://www.apple.com/macosx/upgrade/requirements.html Of course we are talking bare minimum here, slower G3, limitations on system bus, system memory, video memory (no quartz extreme here), limited screen real estate, and so on. Taking these into consideration, I would have different expectations of an original bondi blue iMac versus my 900mhz G3 iBook or my G4 tower. We are talking the difference between running and running well, between running and being practical for a particular task.
