H&V_SYNC - horizontal sync pulse goes to the Raster Timing Generator PCB.
GRN_SYNC - sync-on-green sync pulse goes to the Raster Timing Generator
PCB.
RESTORE - DC Restore control signal to the Video Amplifier PCB. This signal
controls the DC level of the image signal, clamping it to the proper level on the
Video Amplifier PCB.
