HOW IT ALL WORKS

Inputs come in from the game boards (most commonly the Sega G-80 system XY timing and
control boards) and are fed into the input protection board. The input signals then go to the
deflection board, and the deflection board does its stuff. The deflection board sends an "OK, these
signals are cool" signal to the HV unit, which turns on and provides the HV to the picture tube and
the AC to the heater. The deflection board then feeds the color signals to the neck board, and
controls their position with the deflection yoke.
The G-08 monitor has a unique spot killer system, in that if the monitor receives no valid inputs
from the game board, the monitor will shut down the high voltage. This method of self-
preservation differs from that built into the Wells-Gardner 6100 color XY monitor, which, in a
zero-deflection mode, shuts down the Z amplifier, which is like turning the brightness level to zero.
The G08 has no Z amplifier, and must protect itself by more drastic measures.
