Ok... hitting the book again:

60-3056.

    This model is similar to 60-3051 and 60-3054. Refer to section covering
60-3051 to understand the operation of the circutry.

    Power Supply
           This model uses the same type used in the 60-3054 except that the
zener diode CR1 has been changed from 10% to 5%

60-3054:

    Power Supply
        A zener diode is used without the help of a series-pass transistor

60-3051

    cannot find tip side polarity though...( or even part # ) for adaptor

    interesting note from board schematic:

        The AC Adaptor supplied with the TV game is special type. DO NOT
ATTEMPT TO USE ANY OTHER ADAPTOR WITH THIS GAME. It provides 9 volts DC at
225mA...
