A friend of mine gave me three games; TV Ping Pong, Astro Invaders, and Cyber Police ESwat. Pong works but I think the screen image is a little small. Astro Invaders just makes some obnoxious noise when I turn it on. ESwat works but the image is fuzzy. Any of these games significant/worth restoring? I am thinking I may sell two and convert one to a MAME cabinet. Should I bother fixing them, or just part them out? -Greg
