I haven't done this since the old days.... but it's possible to solder a new pin on the CPU.
Use a length of copper solid core "telephone wire", tin the end, and carefully solder the wire to the broken pin location.
Then cut the wire to match the height of the pins. You may want to use a wire gauge that matches the pins.
You'll need a very fine soldering iron tip, and a low wattage soldering iron. Don't go at this with a soldering gun or butane iron.
Use LEAD rosin core solder, not the new antimony lead-free crap. Don't keep the heat on the CPU too long.
I would also suggest one of those magnifying glass lights and you'll need a steady hand.
Another possibility is a jeweler who makes custom jewelry. He could actually solder another gold plated pin on for you.
