[Coco] A Silly MC6847 to HDMI Conversion Idea

[Christopher Fox]

Well, now we’ve come full circle and realized incandescence really is a silly way to generate light, given how much of the energy input goes into waste heat. :-)

    Yeah, silly idea! That's what they said about the guy who some time ago had an idea of generating light by making a wire glow ;-) Salvador

    Last night I had a silly idea for making an FPGA-based module that would plug into the socket in place of an MC6847 or MC6847T1, emulating the original VDG while also generating clean HDMI output for connection to modern displays. It wouldn't necessarily add any new graphics modes, but it would allow very crisp HDMI output with proper emulation of the NTSC color aliasing effects.
    
    While I doubt that this idea is practical enough to actually bring it to reality (e.g., I would anticipate a total worldwide market for about one of these devices, counting myself), I do wonder whether anybody else has played with any sort of drop-in MC6847 replacements to add functionality to the CoCo 1/2 or any other vintage systems that used the MC6847.
