NOTE:

SOU PCB: The P1 connector only outputs amplified sound if a
sound amp is installed on the board. Generally, this amp was not
installed and the P2 connector was run to the audio amp pcb located
on the monitor.
The Pn designations for the connectors may vary from board to board,
but the pin connections still remain the same.
All power and ground connections on Power-in connectors are supplied
from the power supply. All power and ground connections on other
connectors out outputs, for controls or auxiliary lights and counters.

*     On two board Donkey Kong and Donkey Kong Jr boards,
       these connectors are moved to the main CPU PCB

**   Only present on Radarscope and TKG2/3 boards

*** On TRS-01 board sets, this connector is on the ESS board

All board sets use Mitsumi shrouded black headers on the PCB, with the
exception of the TKG- board sets which use JST NH headers instead.

Other notable differences on the TKG set, besides using JST NH headers,
they all had an audio amp installed and put out non-inverted colors.
They also did not require +24V needed for the coin counter.
