Your wording seems to imply that you still think NT was built on some
earlier MS product.  It was written from scratch by a team recruited
mostly from outside MS, including the leader, a guy who was I think
experienced in VMS development.  The names escape me right now.  But
there were a couple of books, by Helen someone, I think, which helped us
outsiders understand some of the philosophies of the development.
