It seems like Unix is largely a child of the coasts.
We can add the eastern coast of Australia, where the original Wollongong group made the first V6 port to the Interdata 7/32 (not to be confused with the Labs port to the 8/32). The Western U.S. company of the same name was formed to sell it, but I don't know if any of the Ozites moved to Palo Alto.
