Interesting rates – especially the commercial rates. At these rates, my work on a single five-month project alone at the time would have had a direct cost of roughly $7MM, and over $640MM in resources for QA (we were running 16 engines, and sometimes more, 24x7, on machines significantly faster than the 3090 at the time).
Here are two PDFs that give the final rates on both MTS machines at Michigan. These are the contents of *RATES and *RATES.UB as of 1996. They mention a file *ALLRATES that is said to contain rate history, but this file seems to have been destroyed some time before 1996. Too bad, it would be interesting.
