More Atari 2600 Video Mods

November 14, 2025

I regularly browse eBay, Vinted or Willhaben in search of retro computing/gaming hardware. Whenever I come across an Atari 2600 that's listed as "non-working" or "untested" (usually mean non-working as well) I just can't resist and have to buy and try to fix it.

That's why my desk looks like this on a regular basis.

One thing I often do after a successful repair attempt, is adding a composite video mod to these consoles (as described here or here). I typically resell the repaired consoles and many people nowadays have no use for (or don't understand) the RF cable.

The simplest video mod consists just of a couple of resistors and a transistor. I used to make these mod myself on a piece of perfboard but it just doesn't look as nice as an actual printed circuit board (PCB).

Luckily I got in contact with PCBWay who were kind enough to support me with this project and sponsor my first batch of PCBs.

Thanks PCBWay for sponsoring this blog

They even have an existing Atari 2600 Composite Video Mod PCB readily available.

What I especially like about this mod is that it can be soldered directly to the 5 pin header where the RF box was previously connected. That way it becomes an integral part of the 2600's mainboard.

The installed video mod

So there I went, fixed up this bunch of Atari 2600s, installed the video mods and got rid of the chaos on my desk.
