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. (https://www.amazon.com/Soul-New-Machine-Tracy-Kidder/dp/0316491977/ref=sr_1_1?keywords=the+soul+of+a+new+machine+by+tracy+kidder&qid=1668271720&sprefix=the+soul+of+a+new%2Caps%2C233&sr=8-1). It was originally written in 1982 - 40 years ago! Clem Cole wrote: > This recent activity on the simh mailing list WRT to DG Nova and > Ecpilse got me wondering.
