GC0  Game Controller 0 input.  An analog input designed to accept a
     variable resistance in the range of 0 to 150 K ohms.  Each GC
     input is part of an analog-to-digital (A-to-D or A/D) conversion
     circuit that allows an analog resistance value to be converted
     into a digital quantity.  The resistance forms part of a simple
     RC (resistor-capacitor) timing circuit that sets the time
     constant for the 558 integrated circuit (a quad version of the
     555 Timer).
GC1  Game Controller 1 input.  Same as GC0.
GC2  Game Controller 2 input.  Same as GC0.
GC3  Game Controller 3 input.  Same as GC0.
PB0  Push Button 0 input.
PB1  Push Button 1 input.
PB2  Push Button 2 input.
