Hey guys, At my school my multimedia teacher is trying to get three different Power Macintosh G4 Mirror Door Drives to work. All of them have at least one different thing wrong with them, let me explain. All of them are 1GHz G4s (if I am correct), 512 MB RAM, and 80 GB HDD's (if I am correct, again). All of them are running 10.2 (factory installs) . (We're not the kind of school that keeps the computers up to date). I believe we have all the restore CD's for these computers, however we do not want to reinstall the OS due to we are looking for specific files on them (video footage). #1: This computer used to work but was highly unreliable. It would take literally 5 minutes to boot, the superdrive has a disk stuck in the drive and will not open, and would lock up constantly and gave kernel panics. About a week ago we decided to open it up to take the RAM out of it, however found out it wasn't compatible with Quicksilvers and put it back in. We tried booting it up today, and it made a loud BEEP noise and turned back off. The RAM is secured. #2: This computer will not turn on. The monitor receives power (studio display LCD) but I believe the power button is broken because it goes farther in than what it is supposed to. We currently have been using this machine to try and get parts for the others. #3: This G4 will turn on, but will not output picture to the display. The light stays lit and it sounds like its booting up, but we've tried two different monitors (Studio LCD's) and none of them would show picture. The power light stays orange when connected to them. For the most part, we need enough advice to get at least *one* machine operable, and then we will need to know how to transplant the hard drives out of these machines to look for the files we need. We tried getting the hard drive out of one but we couldn't figure out how to open the caddy that they are in without prying it open. Many thanks and hope you can help! We've tried researching this, but due to we're looking at 3 different problems on 3 different machines we were fruitless. Jake *Also note some of these machines appear to have two internal HDDs, maybe 2x40GB?
