Now that you mention 2.9BSD, you jog my memory.  Originally, 2BSD did 
not contain a kernel; it was just userland tools.  3BSD was for the VAX 
(not the PDP-11 as I said earlier), with virtual memory (based on the 
swap-only port from AT&T called 32V) but not networking.  4BSD added 
networking.  2.9BSD came later, and included a complete PDP-11 system.  
If I remember correctly, 2.9 came after 4.0.
