    I'm trying to resurrect a neglected iMac G3 Graphite (runs at 600MHz). It's still running OS X 9.2, which I plan to replace with OS X once I resolves the iMac's issues. Here's the main one:

    Every time iMac is unplugged, it loses the date and time and sets it to 1/1/1901 at noon.

    Obvious solutions:

    I tried that, using two batteries I know work. Same problem.

    - I did that, using COMMAND-OPTION-P-R at startup. The "dong" goes off twice, indicating successful reset, and yet still problem exists.

    I've also tried full combination -- insert new battery, and at first boot up with new battery, immediately reset PRAM. Then set the clock. Shutdown. Take off power. Plug back in. And there it is -- forgot the date and time.

    I suppose this is something that could be lived with, but I'd like to find a solution.

    Any ideas?
