So, a friend of mine who owns a game store got this in a bundle of Atari games. He's never seen anything like it, and gave it to me wondering if I knew what it was. I have never seen anything like this, so I ask you all, anyone know what this is? I plugged it into an Atari, and I couldn't get it to do anything.
As you can see, it has these strange pegs coming out of it, and has this label on the back, but I don't know what they might do, and what the label means. The pegs are perfectly poked out of the casing, with no scratches around them, making him think that they were not made by a person, but I'm not sure. I think it looks like a regular Combat cartridge that has been modified. I have it with me if anyone wants me to upload more photos of it.
Thanks in advance for any help identifying this thing.
