So, I might be buying a broken PowerBook G4 today and I was wondering what you guys think. Please help if you can with the following questions. First of all, the owner "lost" the power cord, so I need to know if my Rev. D PowerBook G4 power adapter will work with this machine. Second, it's model number is A1025 and I'm trying to figure out what the specs could be at worse. Third, the screen is busted, someone sat or stepped on it apparently, so does this machine have an external display port of any kind? So, assuming I can bring my PowerBook G4 power cord to test that it at least powers up, is this thing worth $75? I'm more than happy to use it with an external display if that is a possibility. Thanks!
