Early on, I noticed some similarities between VMS and Xerox CP-V.

At a conference 15 or 20 years ago, I ran into Andy Goldstein and asked 
him about this.

He said that, yes, there were 1 or 2 members of the Xerox CP-V 
development team on the VMS development team, but he didn't remember 
what they were responsible for.

This is all anecdotal.
