Volgens Apple Insider heeft Apple moedwillig G3's gemankeert waardoor deze niet overweg kunnen met toekomstige G4 upgrade cards:
According to the source, "Apple has intentionally disable the ability to use a G4 processor card in the current Blue and White G3s via its new firmware update. We know this was done intentionally because the previous version of firmware does not have a problem with the presence of a G4 processor." [break]...en de reden hiervoor volgens The Register:[/break] So how likely are the rumours to be true? Circumstantial evidence suggests they might well be. With a die size many times larger than the current PowerPC 750 chips (see Naked PowerPC G4 seen on Web) yields on the new chip are likely to be low, pushing up prices and, more importantly, limiting supply. Preventing existing G3s from working with the G4 would severely limit the demand for upgrades, in turn cutting down the number of chips upgrade manufacturers require, and thus increasing the number of chips Apple can buy.
