I sent an email to Matt at Atari Protos, he seemed interested to see pics of the contents of the item. Im thinking its probably a Reviewers copy or a Final version Beta test copy ( or a Store Demo copy ) due to the copywrite year being 1983 ( regular cart is 1982 ). BUT I told him when I get it in the mail Id share pics and anything I notice different in the game play. Also he wanted to see if I could get this dumped and I guess have it checked to see if its the same as the final version . He doesnt recall seeing a Revisision with a letter. REV . A compared to REV. 0 or REV. 7 ( like in AtariWriter ).
If anyone has any info on this cart feel free to fill me in on it. Its an interesting find that didnt cost me all that much. Coolness factor more than paid for itself.
