Interesting. It would generate a PAL-clocked black-and-white signal (with what would be NTSC artifact colors, except in PAL they don't artifact), and then a separate circuit would read that and generate the colors based on the pattern. There also seemed to be "International NTSC" models that would output NTSC color at 50 Hz and only worked with Apple's own displays... https://nerdlypleasures.blogspot.com/2021/10/apple-ii-composite-artifact-color-ntsc.html https://nerdlypleasures.blogspot.com/2021/10/apple-ii-compos... > The PAL Color Encoder Card would tap into the video signal, convert every pixel into a 4-bit value, assign the correct color and generate a PAL-compatible 4.43MHz color signal running at 50Hz with colors assigned according to the pixel patterns
