The sun2/sun3 simulator (tme) should boot netbsd out of the box.
http://people.csail.mit.edu/fredette/tme/
I have mods which will allow it boot early sun os version (sunos 2.0,
3.2 & 3.5).
Everything works except the ethernet on 3.5 - I need to fix that.

(I miss my old sun-2 :-)
The code is pretty dense but also pretty complete. The sun-2 is 68010
based. As I recall
the sun-3 is 68020 based. I can't remember if there were any 68030
based sun's.

Brad Parker's version of the MIT Sun simulator may be able to boot BSD.

The Sun 3/80 and 3/400 are 68030-based machines. The SunOS kernel
architecture name is "sun3x".

All custom, implemented in SSI, PALs, and/or gate arrays.

The 2/120 for example has a lot of 74LS chips... The CPU board IS rather
heavy.
I should get the machine running (have a ST512 disk now.)
Will probably have to netboot.
The tapes isnt' dependable any more and last time i tried the machine,
the tape station gave me trouble.

3/80 and up seem to be o3o based, according to Wiki.

That would be the sun3x. Came in the same case as a spare :)
