After acquiring an Atari 2600 to install the 2600RGB kit I was surprised by the extreme level of picture and audio noise when connecting the system to my HDTV using the stock RF switch output! Thankfully the 2600RGB clears things up in both picture and sound departments.
I installed the kit in a "heavy sixer" several months ago, but hadn't finalized the output wiring until today! This was in part due to the metal casing that surrounds the main circuit board. Tim's installation guide for this particular revision of the Atari 2600 suggests using small wires to run underneath the metal casing, but I decided to take another approach!
2600RGB kit installed, but in need of output re-wiring.
What was the other approach? Drill two holes in the metal casing! One for the audio and video signals, and a second smaller one for the palette toggle button.
I decided to use a 8 pin mini din extension cable with a "XRGB-mini" pinout so that I could utilize the existing system shell opening that had been used for RF output, and conform to pinout that does not require any external components.

was previously used to secure the RF output cable.
All connected and ready for testing!
Success! No troubleshooting required!
