The RGB output of IC4501 and the OSD (On Screen Display) RGB output of the
television MPU, IC001 enter the RGB amplifier IC4512. A switching circuit
combines the two RGB signals for display on the screen. The Adjust Data section
sets the RGB level, matching the required levels for the DG board. The output of
IC4512 enters IC8200 of the DG-Board for selection between PC and all other
inputs.
