    So a guy on ebay is selling a custom upgraded/overclocking for a 1.5ghz Powerbook G4. Is that possible? I've never heard of anything like that before :confused:.

    It is possible. Many PowerMacs, eMacs, Mac minis and other systems are overclocked by changing some resistors around on the logic board that change the bus multiplier (Bus Speed X Bus Multiplier = CPU Speed). I'm sure its possible on the PowerBooks as well. The biggest issue that would face a system with such a high over clock is stability.

    The heat of such an overclock would cause problems too, and probably burn a hole in your lap if you used it!:p

    Seriously, I would pass on that. The minimal performance increase of overclocking is not worth the increased possibility of system failure. IMHO

    It just looks like it's been upgraded with a 3rd-party 7447a CPU.

    The 7447a actually does a decent job of boosting performance, largely because of the improved (and I think larger) cache architecture which helps relieve the completely saturated memory bus on the PowerBook G4s.

    http://www.barefeats.com/pb183.html Barefeats did a review on it.

    I like how the guy says his powerbook now runs faster than his MBP. Either he's still running CS2 via rosetta on an older MBP or he's completely full of ****.
