I used an MV/8000 ("Eagle") when I was writing video game cartridges for Atari. I never really programmed it -- maybe a little scripting in their shell -- but just used it for cross-development to some home computers. The system rarely crashed. I was used to 4.2 bsd, but the DG was still a nice system. It got bogged down during the day with 40-50 users running an awful little email and office automation app, but it was fine at night (just like the mainframe at my university). The shell struck me as a cross between VAX/VMS and Unix. The file system was pretty decent. The screen editor that DG provided worked well, and though I missed Emacs, it was adequate for writing largish programs. (There was a DG equivalent of TECO that I tried to learn, but it was about as opaque and terse ("badly designed") as the original TECO and I just gave it up after a while). All in all, I was pleasantly surprised with how well it worked.
