[Drich290195]

Hi what’s the difference between the G4 (1.1) and (1.2). I have two PowerBook 12 inch G4s. Under the about this Mac one says the processor is a 1.1 the other a 1.2. What’s the difference? Can’t find from google thanks.

both are the same clock speed to add 1.33Ghz

The 867 uses a 7455 cpu, the 1.0 has a 7447 and the 1.33/1.5 have a 7447a.

I don't see a 1.1 or 1.2. Here is a listing of the Powerbook G4 models. They should have a model ID like Powerbook 6,1/6,2/6,4/6,8

The "rev" is less important than the type of CPU. There were several different CPUs that apple called "G4" and the rev is basically the tail end of the PVR. For example, two very different CPUs can have the same rev. Also, I think you can (and may need to) fake this out in the system profiler. Here is a list showing some of this:
