Hi, The First Unix port was made in 1977 by Richard Miller in the Computing Science Department at the University of Wollongong. http://www.uow.edu.au/content/groups/public/@web/@inf/@scsse/documents/doc/uow103747.pdf https://www.usenix.org/legacy/publications/library/proceedings/usenix98/invited_talks/miller.ps
I think that he is the same Richard Miller who did the Plan9 port to Raspberry Pi, right or am I wrong? Antonio
