Galaxian harness and joy stick and buttons and power supply. I tested this and it powers up, but the picture is a jumbled mess. I think it's complete, but a speaker and coin counter. May just be the smaller rom board. Looks like it has a few jumpers. Will be sold as is. 60.00 bucks shipped. Will ship USPS parcel post. Let me know if you want it. It's a project. Thanks for looking. This is a picture of what it is doing.
