I just completed my first Raspberry Pi PICO project. It takes the RGB from the CoCo 3 and converts it to XGA. There were two pictures shows the difference between CoCo 3's RGB and CMP at Width 80 but they make the post too big. (I am new to posting here) There is more work to do and I will post more as I improve the conversion. Currently the CoCo 3 RGB is 256 pixels wide with 192 lines when the Width is 32. This expands to 400 pixels when width is 80. Therefore I converted 400 pixels by 192 lines for all CoCo widths. XGA is 800 x 600. To use as much of the screen I doubled the width of CoCo pixels and repeated each line twice. When I learn to post a video with my daughter's help I will let the group know where to view it. Bruce P.
