I have a Power Mac G4 model no. M5183, serial no.XB12308DKL1, that I thought was a "D/A" model since it has a 733 MHz processor. When I search for model numbers in MacTracker, the model number says it's the AGP Graphics model (max processor speed of 500MHz) or a G3 Blue and White (max processor speed of 400MHz). The labeling on the back of the Mac appears to be original, so what exactly do I have? I'm confused and would appreciate some clarification. Thanks for the help.
