I’ve seen it said a couple of places that the DG/UX kernel was an almost complete rewrite and rather well-done.

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).

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. :)

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.

Never seen it in the wild, sadly.  Hope it does appear at some point.

I have to agree with Clem here. I ported multiple device drivers for custom boards to DG/UX and it was nicely done at the lower levels.

The documentation was excellent and the field service reps were more than helpful when I walked into strange corners that didn’t perfectly mesh between SunOS 4.X and DG/UX.
