One of my odd bits of computing history is that I have used both an original Bell Lab Blit terminal and the later AT&T DMD 5620 commercialized version of it, and in both cases by choice and with the host software that made each into an interesting windowing environment.
(My X window manager root menu still (sort of) mimics the Blit's menu and is called 'Blit' in my fvwm configuration file. It used to be much closer to the Blit's, but things happened over the years.)
