I've got Model No. 60-3056. It takes six C cells to
run. So that means
that this baby should run off of a 9 volt power supply.
What should the tip polarity be? I better not get my trusty VOM out and
check that would be too simple. I know what I'll do. I let all the guys
on CLASSICCMP argue about it! Heh...Heh... Why should I do all the work?
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...
