This is my first attempt to explain how the NTSC-only 8-bit color modes work on the Tandy Color Computer 3. After devising a theory about how the mode works, I built a simulation of how I think the mode works and coupled it with a simulation of how I think an NTSC decoder would interpret the resulting signals. I used the results to calculate a palette map and in the video I show how it compares to the actual output from the CoCo3.
