It's interesting history though. I never realised there was a "pre-  Joy" iteration of SunOS, which your remark led me to discover, via http://www.unisoft.com/history.html and other sources. To clarify, this was SunOS - not what is today called Solaris, which is at heart AT&T System V.

Jorn Barger has an interesting timeline: http://www.robotwisdom.com/linux/nonnix.html

1. 25Aug: Microsoft's 1st-ever os 'Xenix' announced for 8086, Z8000, 68000, and PDP-11, based partly on BSD [cite] [cite] [history] 1.0 based on v6 [cite] ...
2. Andy Bechtolsheim starts licensing Sun board for $10k [cite] 6 or 7 sales in 1981; 1st is Codata (ports Lucasfilms/Sprocket Unix and UniSoft) [cite] ...
3. Jeff Schreibman founds Unisoft and writes UniPlus [cite] [history] ... no-date: Sun hires UniSoft to create 'stopgap' Unix [cite] adds MS Xenix, Lucasfilm Unix ...
4. AT&T's 1st commercial Unix, System III [cite] ...
5. Jun: Sun hires Bill Joy [cite] ...
6. Sun builds 68000-based Unix boxes w/'SunOS' [cite]

"The Sun 1 was shipped with Unisoft V7 UNIX. Later Bill Joy, the key figure of the Berkeley Software Distribution (BSD) and one of four founders of Sun produced a customized 4.1BSD UNIX called SunOS as an operating system for its workstations. Up through version 4.1.x (Solaris 1.x), SunOS remained a heavily BSD-influenced Unix implementation."
