I've been studying the terminal logic board from a Heathkit H19 terminal, and the MM5740 Keyboard Encoder that it uses to convert the keyboard matrix into usable signals. However, I understand that the Apple I and II used this same encoder, and I wouldn't be surprised if more machines also used it.
I'm curious if someone has emulated the outputs of this device to allow for different kinds of keyboards to be used. The idea of turning say, PS/2 keyboard signal like-signals I'm sure has crossed somebody's mind before. Am I completely off my rocker here?
