They were never giving you the full story then. The equipment would be shipped hot back to Waltz Mill where it would be maintained between outage seasons. A system was not dedicated to a single plant but carried between plants. With minor retooling it would be used on 44's 51's and any other generator that you find out there. It was interesting using them in CE designs though.
The cooling issue was solved using a combination of venturi coolers with heat pipes for some components and a tent with a spot cooler for other parts. I don't recall all of the details about the control system but I do remember the erratic behavior of the ROSA I systems. What you are saying might help to make sense as to why they switched to brushless DC motors and multiple resolvers per axis.
Did you ever make it out to Waltz Mill to work at the mock-ups? I probably was there 8 to 10 times a year for durations of at least a week.
I quit working there in 1997 and went to work for their competition in 2000. I moved from Upstate NY to Lynchburg VA in 2001. Ultimately I left the industry in 2008 after the passing of my first wife and now serve as a lowly IT Manager. Westinghouse and Waltz Mill now seem like a lifetime ago.
