Diagnostic Cart Version 1.3


This is diagnostic cart version 1.3.  Notice how the screen says "Press Green Atari"?  On prototype 5200 systems the # and * keys on the keypad were replaced by the word "Atari" in red and green.  It is unknown why version 1.3 refers to the "Green Atari" key but the earlier version 1.1 correctly refers to it as the asterix key.

This particular Diagnostic Cart is housed in an old Missile Command case.  This was a common practice at the time.
