ADB was pretty solid. A shared-single-wire bus that allows multiple slaves by including an address in the message... but includes a protocol-level reset that's used regularly, so a missed single bit doesn't jam things up unrecoverably. When I think of how many fewer hours of my life I would have wasted had I2C learned this lesson...

Has anyone calculated or measured the input lag of ADB vs other protocols such as PS/2 or USB? This is unfortunately hard to search because most references on the web to ADB are for the Android Debug Bridge.
From the numbers given, it seems like ~2ms to send a packet (my math may be off), which is quite good when compared with other contemporary/modern protocols (see: https://danluu.com/input-lag/ for examples)

As the author mentions doing it, a note regarding retrobright: it seems to cause faster yellowing than not using it. https://youtu.be/_n_WpjseCXA
Maybe just let your items show their age.
