I have a couple of monitors that accept the 4-wire RGBs signal, and I want to run older consoles on them via the RCA style composite yellow, red, white inputs.  Or, at least using the yellow, since I would be running the audio straight to the speakers.  I have searched but cannot find anything except for scart.  I dont have anything that would accept a scart connector, so ideally some kind of convertor to accept RCA video into the RGBs would be great.
