The power supply provides all necessary game power as shown in Figure 4-3.
DC is rectified and filtered in the power supply assembly and regulated to a stable + 5 volts DC by the LM323 on the game PCB. The regulated +5 volts DC is distributed throughout the PCB to power all logic circuits (see Figure 4-4).
The game PCB receives an unregulated + 10 volts DC at pins B and 2 of the PCB edge connector. The + 10 volts
The unregulated +10 volts DC also powers the LM324 audio amplifier circuits in the audio circuitry.
