    Probably going to butcher the explanation, but: the idea is you can hook one of these up to the different pins on a microcontroller or other digital chip and note the changes in logic levels over time. So, if you found the pins that change voltage when you press a given key, something like this analyzer will tell you exactly which pins changed and with what timing.

    Just don't make the same mistake I did and accidentally short a chip's power supply to ground!

    I've been interested in this project but haven't pulled the trigger yet.

    You can also go to Settings -> Face ID & Passcode -> Allow Access When Locked and disable everything. This prevents you from being able to open the notification center or control center at all while the phone is locked.

    The only setting I've left enabled here is "Live Activities."

    I've read that a proper serial terminal is very hard to implement. I want to try to do something simple with my SL-500: support sending characters to the computer (and to the paper as I type), and support sending characters, line returns, and backspace from the computer to my typewriter to print on paper. I imagine I'll have to find/adapt some terminal emulator for this to work. I haven't looked at that yet.

    What I've done so far is to take the typewriter apart and find its circuitry that interprets keyboard button presses. I've tried to hook up a logic analyzer to start tracing things out, but I managed to short something out and fry the board. I've got another control board ready to go for a next attempt.

    Oh, that's exciting! I've been wanting to turn an old electronic typewriter into some kind of serial terminal. Maybe this is the month for it!
