Assembly Block Diagram
Figure 1—11 Display PCB/CRT Assembly Block DiagramTwo separate circuits provide horizontal and vertical CRT beam deflection. The CRT raster consists of 768 scan lines in one complete frame with 256 pixels per line. The CRT screen is scanned by a vertical raster, bottom to top and left to right (see Figure 1—12). There is no interlacing during the raster scan.
