I thought V7M and Ultrix were entirely diferent and unrelated things. At least on the Pro, DEC released a betal version of the one (which I tried when it came out) and then canceled it and replaced it by a release of the other. I forgot which came first, other than that the beta was really clunky. As in, a "vi" that didn't do real screen updates...
