Atari 2600 Jr TRRS Adapter

Anyone who knows the Atari 2600 Jr. knows that the shells on those are extremely brittle. A lot of the AV mods to add composite video require drilling into the shell to add RCA ports. This can lead to disaster - ask me how I know! Due that unfortunate event, I looked for an alternate solution to RCA jacks. What I found was the TRRS port, which uses a 3.5mm jack for composite AV. You do need a special 3.5mm to RCA cable. Both the specific port I used for this model and the cable can be found at https://www.retrofixes.com/products/trrs-composite-cable.

This was the no cut solution I was looking for, or so I thought. When I went to insert the TRRS port into the case, I quickly discovered that the opening in the shell was way too big and the port just slipped right through. So, that led me to design this adapter to mount the port.

This is a simple adapter to use the RF output hole in the Atari 2600 Jr case for a TRRS jack. Since the hole in the case spans both the top and bottom
