I was reading a bit about PLATO, a computer system for computer-aided instruction, and it is astonishingly old. It was around in the 70s, the 80s, etc. The language originally used for creating lessons and tutorials was called TUTOR. I’ve been extremely curious about the language since I first read about it on the weekend and I’m glad to say that I’ve found the manual.
I bet there are a few gems in this manual. History is awesome.
