Theory Of Operation

The block diagram in Figure 4-1 shows the major parts of the Sky Raider Came.

The game's television monitor is a self-contained transistorized unit. The composite video signal sent to the monitor differs in many respects from the signal derived from commercial TV broadcasts. The picture appearing on the screen, therefore, is unlike that of a home TV set and the monitor does not produce any sound. See Chapter 6 for a schematic diagram of the TV monitor.

The game's composite video signal produces four video levels instead of the continuous shades of grey seen on a home TV screen.
