This board was originally designed as the analog video amplifier circuitry for my VDU projects, but the origin of the schematic was as a way to add a composite video output to the Atari VCS/2600 and similar consoles like the Atari 7800 Pro System. The original hardware only supported RF output, which was barely acceptable in those days - today you'd be hard pressed to even fit the cable somewhere, let alone get it to work. So here's a composite video mod that's easy to put together and there are just a few wires going anywhere other than what is necessary.

You'll need to add a couple of RCA jacks to the unit itself, as well as locate the proper places to solder the input wires to - there should be plenty of information online for just about every variation out there, so not to worry (just figure out which version of the console you have and search for it). If you can figure out how not to burn yourself on a soldering iron while thinking, you should be able to get it done without too much trouble!

If you're looking for controller options for the Atari 7800, I've also shared projects for putting together an adapter for using a Sega Mega Drive gamepad as well as an adapter for the C64 JoyKEY - both options will allow you to use the second fire button without any of those dreadful original ones.

See documentation link for part descriptions as well as additional information.

NB! This is revision B of the module, it has no significant changes - I just thought it needed better markings on the silkscreen to make things a bit clearer when installing the board.
