I hope I got the connections right. This is the first time I have designed something this large. Videos mods are easy to separate the Digital and Analog components (resistor ladder separates them well). I should have added more ground planes on this but its a prototype so its mainly for testing purposes. The only thing I am worried about is the power converter (switching regulator type Ti PTN4050) might be a bit to close to the clock signal for the Atari but its buffered by a couple 100uF caps so it should be ok.
The board measures 4.65" x 3.45". Has built in power converters (to up a 3.7V Lithium Cell to 5V), audio amp, video mod, and controls for the left player. Stereo jack, right and left difficulty switches, black and white switch (some games use this as a control). Only thing it misses is the Right control port as Serial ports are dam huge.

I think I should just send you my extra screen. I lost the sound on it for some reason, but you hae your own amp built, so I'm sure you can get it working again. LOL
That's pretty cool I hope you bring some with you to the MGC. And really when I saw this for the first time I thought it was just another PCB for minimizing the Atari 2600 size. But seeing a screen, and buttons soldered on it's really much much more then that, and really cool. I'm excited to see what it will look like when you finish it.

That cartridge is neat. I guess it would be kinda cool to have it built in, but it would make everything larger... Incidentally, only mono builtin (I know the headphones are stereo)?
