    The discussion of how phosphor reacts and the dot stretching timing circuitry is mind blowing. The fact that someone or several someones thought of how to maximize brightness and make a good looking front by how the scan line works is amazing

      Yes, agreed it’s an amazing piece of work - thanks for sharing. After decades I finally understand why I like those old school terminal fonts so much.

        Same. I used to feel highly indulgent for paying for Berkeley Mono but at the end of the day. Need to life with flair

      It is!

      Phosphors varied considerably too. Faster phosphors were generally avoided due to the need for low refresh rates and or interlaced display lines.

      An older black and white television, for example, used slower phosphors in order to minimize the impact of interlaced images.

      Similar phosphors in green and amber, to my eye a bit slower, pretty much eliminated flicker at 50hz / 60hz. These phosphors did not fatigue users much.

      Newer, color displays came with faster phosphors!

      Fonts look very different because the response curves are different as this great piece covers well.
