It seems another highly ported implementation of DECnet was TSSnet from Thursby Software
Systems. That software was available for Amiga and Macintosh as well as Solaris and other
UNIX systems.
I've found an announcement that specifically mentions Solaris support:

I've contacted Thursby Software Systems, who sadly
have no information on legacy products at all on their public website.
Hopefully I will receive a response.
