Well you could get it modified so you can relive nostalgic games in stunning clarity on a newer TV or even an older TV with composite/S-Video. I recommend the Longhorn Engineer, he takes great pride and care of classic consoles and gives them a new life with the modern audio/video mods. Of course if you don't want the modification,I'm willing to bet he could solder on a new RF out connector for you.
