I'm pretty sure Berkeley (or UC?) had a System V license and was allowed to redistribute code based on it in BSD. That became a point of contention later, when the *BSDs started to become popular. This is all very old stuff so I might have the details wrong. It was definitely a fun time to be at UCB. I remember getting the early Sun workstations and porting stuff to them. It was a really good port of BSD, but that Motorola chip was a problem for some things. I ported the Franz Lisp compiler (liszt) to it.
