Guess the numbers I was given so many years ago for the models 13/24 may have been a bit off. This chart says 4.5 and 9.9 MIPS, I was told way back it was 3.3 and 8. In either case, a really small computer (by todays standards) to run a 400 bed hospital.

They were the first 2 machines I worked on. IDK if that is extrapolatable to the relative performance your chart shows. I don't have documentation to verify these numbers.
