From the project
A Composite and S-Video Mod for Tandy Radioshack Color Computer 2
The RHCCV is a video mod for the Tandy Radio Shack Color Computer 2. The modification replaces the original video module (the shiny metal box) of the CoCo2. It features a 6-pin or 4-pin compatible Mini DIN connector with S-Video, Composite Video and Audio outputs.
The /jlcpcb folder contains production-ready files that can be directly uploaded to jlcpcb.com for PCB manufacturing.
