I have been wanting to do this for awhile but have not gotten around to it. I took my Open Bench Logic Sniffer and sniffed the e (in picture from top to bottom) of the Atari 7800 MARIA chip. This is what the signal looks like before it goes into the video mod (D/A converter).
I am still learning how this translates into a picture on the screen. If anyone has any insight into this let me know.

I used to offer a variety of A/V mods choices for the Atari 2600 and Atari 7800 consoles. The modification adds a S-video and composite video output to the Atari along with Stereo sound. The mods where very easy to install. If you can solder a wire you could install these kits.
Blank PCBs are just the bare PCB. No other parts are provided.
Atari Modding Service includes the mod and all parts. You ship the Atari to me and I will install the kit. I also offer a “Deluxe” Service which includes gold plated jacks. These jacks are not offered on the kits.
