I have just picked up a 450mhz G4 cube. I've wanted a PPC Mac again for a while to relive the glory days, and am glad to be back in the fold. Will probably have lots of questions so please bear with me! I am running 10.3.9 currently. Three to start with: 1) It has an Airport card but I can't connect to any networks. It can see various wireless networks, but then just refuses to connect with a generic error. Is this likely to be a hardware issue, or just that the old card can't connect to networks with modern security? 2) The cube powers off whenever I lift it up or tilt it. It's not an instant power loss which makes me think it's not a loose cable, it's like it shuts down. Quite annoying as I need to tilt it to swap USB sticks etc. Is this a feature or a problem? I'm not accidentally pressing the power button (that only sends it to sleep when on anyway.) 3) The DVD-ROM reads discs but won't eject. Is this fixable? Any help appreciated!
