The Sega Mark III console has RGB output, but it's very weak. This amplifier will cure the problem.

It may also work with later revisions of the SG-1000 II which use an RGB-capable VDP, but this has not been tested.

• This circuit will need to be repeated for every signal - Red, Green, Blue and Sync.
• The variable resistor at the end is optional.
