Atari 400/800/XL/XE/XEGS systems
· 2 versions exist. One has an older “(Skew Algn” protection method (as used in M.U.L.E., Pinball Construction Set, etc.) and the other with the newer “Supertrack” method (as used in Racing Destruction Set, Super Boulder Dash, etc.). There are also 2 different label versions, which may or may not correspond to these versions – one has a blue dot on it (picture one) and the other doesn’t (picture #2).
