Just FYI - I have a Sun 3/110 that I still fire up. I’d be interested in the 4.X source (
I believe it still ran on it - I have 3.2 on it now ) to be able to patch a few things to
keep it going.
I’ve not looked for it, as I didn’t think it was readily available.

A little known story is that Scooter did the deal with AT&T because Sun
was in trouble financially. As I remember AT&T bought $200M of Sun stock
at 35% over market but the price was we had to dump SunOS and go to SVr4.
I worked for Ken Okin at the time, senior VP of all server hardware.
Ken paid me to argue with the execs for 6 months to try and reverse this
decision so Ken didn't know the details either.
SunOS 4.x was the bees knees, it was the most well thought out Unix ever.
I got there around 4.1 or just past 4.0 and I didn't know shit. They made
me do POSIX conformance which made me go through every code path. Nothing,
nothing, nothing, and one day it was like the fog cleared and I saw what
they were trying to say. And it was pretty cool, SunOS 4.x was pretty
object oriented without all the nonsense, just the good stuff. SunOS was
the only Unix that just made sense, I could guess what the kernel would
do and 90% of the time I guessed right. I miss it.
That said, Sun never made that OS SMP. Real SMP. Warner says Solbourne
did, I'd still like to, or get Dock Williams or Anil, to talk to the people
that made the VM system scale.

SunOS 4, though I love it more than most people, is ancient history and is
basically under one big lock for SMP. It was a huge amount of work to get
that code to scale in Solaris (they lifted the VM system and the hat layer
from SunOS 4 to 5 and then went to work).
SunOS 4.1 was the best *ix I have ever used (and I've used lots over the
decades); then Slowaris came along and trashed the joint because the suits
were in charge instead of the real workers.
