Huh, this is rather interesting. Two months ago someone contacted me saying he was given a bunch of Atari 2600 carts, including what looked like a Pink Panther prototype. He sent me some pictures, and it actually had a Probe 2000 Pink Panther prototype label on it. It also was in a Probe 2000 cartridge, and the label looked authentic (I think I showed it to Tempest). Very odd that one is now up on eBay without this label. The person I spoke to said he was going to try and find a 2600 to test it on, but I did not hear back from him after my last reply. It doesn't appear that these are the same carts, as it would seem odd that someone would remove such a label. Also, the other individual was not located in Georgia.
Wonder, just curious, if you buy this are you going to allow it to be dumped and shared? You don't have to answer publicly if you don't want to.
