No relation to either V32 or V7. When we started the project we used the existing version of UNIX that we were selling on the PDP 11/45 and PDP 11/70 computers. I believe it was V6. I wrote a lot of documentation and gave a lot of talks and presentations on the system, but never kept any of the documentation myself. There may be some documentation in someone's archives but I did not keep any.
