Figure 4-1 Game Block Diagram

On the game PCB schematic diagram. Figure 4-2, the symbol "P" (appearing at various inputs of integrated circuit devices) indicates a connection of i 5 volts DC through a pullup resistor. For easy reference, the game PCB is divided into grid sections. Along the short side of the board these sections are identified by letters A through R(skipping letters G, I, O and Q because they may be easily contused with the numbers 6,10, and 0 respectively). Along the long side of the board the numbers 1 through 10are used.

Figure 4-3 is a harness schematic of the entire Sky Raider game. This figure illustrates how all electrical and electronic assemblies are electrically connected together.
