Here is the stupid people's text version of the mod. Open up the atari, and take out the metal shield. On the front, there is the chip all the way to the bottom. Flip over the board, find that chip's pins on the bottom of the board, the bottomost chip. On the bottom section of the chip, from right to left, count two. Follow up that lead to the resister. Solder a wire for luma on that resister and one to three in the row to the left. For chroma, solder one more to the left. Combine for the standard video. From where u soldered the chroma, count two left, one up. That is the audio. Solder a wire there to the a/v jacks u bought. Solder a wire from the ground of the jacks to the metal band that the metal went on. Turn the atari on! Here is the short way for just a/v. Follow that chip's lead mentioned earlier. Including that spot, solder 5 wires in a row to the left. Then count two left, one up, solder a wire there. That is audio, the 5 is video.
