To be determined: Did you get the manual with the E.T. Book Cart? If not, I am sure Albert Yarusso still has the PDF file and can print you off a high res manual. I think if your organization bought the E.T. Book Cart right when it was released and you did not return it to Atari Age, you have a first printing of the cart. This means it has the Zero Page Load Error which means that on 4 switch Atari 2600s it works fine. BUT on the 6 switch Atari 2600s, the screen will roll. Michael Rideout can explain it better. Otherwise you have the second printing. (From personal correspondence with Charles Gray, 5/15/2013)
