I connected the audio from the CoCo connector to the left and right audio on the SCART connector. I connected the CoCo 3's composite video to the composite video/sync on the SCART connector and I connected +5V to a 100 ohm resistor connected to the "fast switching" pin on the SCART connector. I then plugged the SCART video connector into my SCART --> HDMI converter, which I plugged into my TV. Viola! Perfect RGB video up scaled to 1080P.
