I worked on 6000 and Cyber 200 systems and didn't have much contact with
the 3000 series. It's darned interesting the amount of dissimilarity that
CDC operating systems had from one another. 6000 SCOPE and NOS was nothing
like MASTER or MSOS. 7000 SCOPE bore a cosmetic resemblance to the 6000
version, but was very different internally. Cyber 200/STAR OS was a
completely different animal from anything else. If you moved between
hardware lines, you might as well have been changing manufacturers.
