So, is the SunOS code available in a way that would let people hack
on it? They had ported it to 386 (roadrunner?), so maybe it'd be
possible to revive it and bring it into the 21st century.

The Googles tells me there's a dozen download places.

I found both 4.1.4 (aka Solaris 1.1.2) and 4.1.3 (which still has the m68k, sun2, and sun3 bits in it).

It’d be quite fun to walk through Bill & Lynne Jolitz’ Dr Dobbs 386BSD articles but with one of these as the starting point.
