So in a complete thread-derail last night, I got into a very enlightening discussion with Zylon about the color output of 4-Switch Woody models. He mentioned that Rev 14 and 16 boards typically have very good color. I noted that my Rev 14 actually had rather poor color, at least as compared to my Light Sixer. Zylon helpfully pointed me to the Atari VCS Field Service Manual; I actually have downloaded this in the past but never paid this particular section much attention. If you have this document, see page 154 , Tech Tip #4:
So I did this little mod this morning and damn, what an improvement! The color now is just about completely on par with my Light Sixer. Fantastic improvement for the level of effort involved. So if you have a 4-Switch Woody with less-than-great color output, a quarter-cent 820 Ω resistor and five minutes of your time can make an incredible difference.
