  • Thanks for sharing. I have been enjoying Davids content for many years and hope he keeps making awesome stuff. The Time Rift Arcade has been neat too.

  • Could you accomplish something similar with just colored foil? Like, red foil makes red and white look the same.

  • You could use the hot lines from RBG as the binary id (2^3) of the monitor and then average up the RBG intensity from the hot lines as the result. This would give you 8 monitor support.

    Or you could limit it to 3 monitors but two hot lines pick the monitor and then you can sum the intensity on those two hot lines two double your fidelity.

    If you do the two line color system you could have a YC signal of luminance (Y) and chrominance (C) and thus you have a color signal.

  • I started seeing LED displays on store fronts in the late 80s (the ones that scroll text horizontally).

    This would have been quite the product then. TVs were expensive, but B&W TVs not so much.

  • Spoilers:

    The trick was pretty easy to guess but still a lot of fun to see put into practice. The EGA monitor bits, and more broadly just the idea of trading color bit depth to multiplex signals for multiple monitors into a single framebuffer and physical output is pretty cool. The Windows display driver idea actually implemented on real hardware would be tons of fun. I could have seen products actually doing this "back in the day" to do multi-head setups. I'm kinda surprised examples don't exist.
