The video chip on the ADAM actually outputs color difference signals natively which is mixed to composite video. Component video is basically the same as the color difference signal (The 9918 used in the TI and Coleco Vision do output Composite video directly though... all the standalone ADAMs I've looked at use the 9928). You can also mix the signals to get Analog RGB and the picture would be considerably better. I used to have an OPA TI Image Maker that plugged into an ADAM years ago (that used a Yamaha V9958 which is largely software compatible with the TI VDP), and with the RGB output on it the video was considerably cleaner than the composite output.
