I was looking for a way to send A/V (not RF) to my monitor. So I have an A/V to VGA converter, the problem was the RadioShack Color Computer only has an RF out, not A/V. Thanks to Dave Jones at EEVBlog, he helped me locate a partially attenuated video signal, after that an audio signal was obvious. I didn't use pin 14 from the composite chip, instead I used the attenuated signal input on the RF Modulator just outside the circuit box. I circled and labeled the pins that I used to jump it to. Since it still needs attenuation, I just turned down the saturation and brightness. I looks clear and the signal is acceptable. Audio also needs attenuation.
