RGB port
    Flicker-Fixer
  • doubles the horizontal frequency of all 15 kHz screen modes to 31.5 kHz - other screen modes are passed through
  • removes flicker of interlaced screens
  • connects externally to the 23 pin RGB port
  • being an external unit, it has to encode the RGB signal, flicker fix, split to RGB and sync again - this reduces the quality of the video signal
  • sync delay adjustment potentiometer
  • claimed to be compatible with the Video Toaster and all genlocks, but it's not in many cases - the genlocked video signal is passed through without scandoubling
  • scandoubled screens are much darker than passed-throughed screens
  • high power consumption - the screen may go darker when the floppy drive is accessed
