Mention: replacing the optical-drive is really tricky and needs repasting the heat-sink, after removing the bottom (info at iFixit). A restore of the original software is the most convenient and original way to approach that machine (the early versions come with a dual-boot os9/osx&classic restore). If you know the exact version of your iMacG4, then it might be possible to find an original install- or restore-medium to start with (or the iso-image) and run installation with the help of the 'external' optical-drive solution mentioned above. You might get an external FireWire-optical-drive for booting / installation as well.ĭon't know, if booting from an external USB-optical-drive does work - but presumably it's not working with USB1 or os9. If you have another Mac with FireWire-socket and working optical drive, you might use that for booting / installing (by booting that other Mac in TargetDiskMode and connect both Macs via FireWire using the ALT-key on booting of the iMacG4)

Most is already said: Macintoshgarden as an os-source, tricks to eject the optical drive, Tiger as the 'last' OSX to be installed without tricks, TenFourFox/TenFourFoxBox(osx) and Classilla-browsers(os9). Often the simplest way is to start an FTP server on the Mac running a modern Mac OS X release and then using an FTP client like Fetch or Archie on the much older Mac to directly download the packages to the older computer. The second option should say Mac OS X Install DVD. I have also included a bootable image of the installation media, should you want to install your own clean virtual machine and/or physical hardware.
