Hi, I just got a 15" Aluminum Powerbook G4 at 1.2 GHz off eBay for $75, and it runs Leopard (It was due to something I mentioned in another thread). I'm almost sure this will be my main computer for at least 4 years. Does anybody know how third-party power supplies work in G4's? It comes with one, and the people I know have had bad experience with third-party adaptors. Are most third-party power adaptors okay in the G4's or are they likely to burn it out? And, is an AirPort Extreme card pulled from a water-damaged iBook likely to work (It won't boot so I can't test it)? The one that I ordered didn't come with an AirPort Extreme card.
