I was impressed with the tooling as well. I worked at the University of Washington in Bio-engineering, and we collaborated with the Department of Radiology. They were building up the first PET scanner at UW, and the PI on my project was simulating mass transport and exchange in the tissues of the myocardium.
We all had a couple of MV/10000s, and I think four MV/4000s. Radiology ran AOS/VS, while we ran (first) MV/UX and later DG/UX.
I really admired the C compiler. It was a first class piece of work, in my view. I believe it was largely written by Michael Meissner.[1]
Thank you for bringing me up to date.
