The video has photos from this site of my C-116's motherboard, (~5:30).
Screen shot from my C-116 (upgraded RAM) running the Tutti Frutti game. Full color.
One other thing; the presenter's said he could not get his C-116 to display in color on his PAL monitor in the UK. The presenter must have had issues with his display or cables. The 116 video is identical to the other TED machines, maybe he had something wrong with his.
