While Larry's described how Berkeley got into it, PWB was not a precursor
to version 7.  Feel free to flame at me if I make a mistake, but I
think it was something like this:

			Early Research Versions
				|
			Version 5 - first version to see light of day
				|
			Version 6 - where I got my start
				|
		+---------------+--------------------+
	   PWB UNIX (Vers 1)                         |
	Semi-supported version        (Troff and early version 7 compiler
	 with RJE features			released here)
		|				     |
		|			         VERSION 7
		|				     |
	UNIX/TS and				     |
	   PWB UNIX (Vers 2)			     |
	(included V7 kernel features)                |
		|				     |
		|				     |
		|				     |
		|				     |
		|				 Research Version 8
	     SYSTEM III				(WOW! I could have had a V8)
	   Finally THE Unix	
		|
	     SYSTEM V
	Well, consider this standard
		|
	     SYSTEM VR2
	Well, consider it a moving target
