[TUHS] Re: DG UNIX History

I'm pretty sure that DG never ported DG-UX to the Nova. There was a native port to the Eclipse (32 bit). There was also a Eunice-style Unix environment that sat on top of their native OS, whatever it was called. When I was working there, DG gave the Georgia Tech School of Information and Computer Science an Eclipse running their native OS in the early mid-80s. I didn't do much with it, and I suspect that nobody else there did either. I'm bcc-ing Scott Lee, who was the admin for that machine at the time; maybe he remembers more. There was a guy who worked at DG and contributed a lot of the Motorola 88000 code to GCC whose name I don't remember, although I met him at a USENIX. If someone else remembers who this is, maybe he can be tracked down for more info. DG-UX was a pretty generic SVR3 (and later SVR4) system, IIRC. In any case, DG-UX on the Eclipse preceded it on the 88000. I hope this helps, Arnold P.S. For the youngsters here who've never heard of it, I highly recommend Tracy Kidder's "The Soul of a New Machine" about the development of the Eclipse.
