I’ve seen it said a couple of places that the DG/UX kernel was an almost complete rewrite and rather well-done.
Indeed - we worked with it at Locus and was one of the simplest kernels to add things too. The locks were easy to understand and it was well documented/thought out.
Have any details been preserved? There’s not a whole lot out there that I’ve been able to find about DG/UX or the AViiON workstation series (whether 88K or Intel x86).
Never seen it in the wild, sadly. Hope it does appear at some point.

PS - I’ve found that my asking around has prompted some people to put things online, so may as well keep asking in various places. :)
