Yeah, I think it's pretty cool too! Well, I can say that it came from a private collection in California.
Actually, there is a link of someone playing this on YouTube (the person who played it I don't think is playing the acual disc, just emulating it on pc) There is one other of this particular prototype release that I know exists. These almost never come up for auction, as collectors are really holding onto thsm now. For me, it's time for someone else to enjoy it. Thanks for the welcone by the way!
