Just that "DECsystem-10" grew from "PDP-10" - that it was mostly a naming issue & not one of any real fundamental difference. There may be some technical distinction, but it seems of little consequence. Same processor. Same instruction set. Maybe some evolutionary differences, but that's true of all significant systems over time. (How long have you been able to buy a "Ford Thunderbird"?) > | PDP-20 n.

As I recall, the University of Chicago had a DECSYSTEM-20 - but I never actually got to touch it. What I saw of the data on it tended to indicate that it used the same KL-10 processor as the DECsystem-10. (KA, KI & KL were the iterations of the processor I remember.)
