In this instance, I speak only for my own terminology and not as an
authoritative source.

My first hands-on experience was with a Personal Iris in 1988.  Except

Ya know, there was a time when I was thinking that I would create my

By "Stanford CPU", I assume you mean the original design for the
processor boards in the workstations that became known as SUN
