While doing some reading about RTTY, I went down a rabbit hole that led me back to vintage computing. Reading about the IBM Selectric I learned there was at least one variant that was used as an interactive terminal for some home computers. Specifically, the Trendata 1000. Was this the only instance of this? Is it possible to interface any old typewriter with a computer provided the proper connections are able to be made? I may be over simplifying it - ASCII conversion from the electrical signal would need to occur, but since I don't know anything about typewriters in this regard, I wouldn't know where to start. I guess for the earlier ones (that were electrically driven purely mechanically) a great deal of work would need to be done to even read the different key presses?
