RSTS/E would like max memory (124 kW on an 11/45), though less will
work -- depending on version; for example V5A runs fine with 48 kW.
And RSTS V4 uses 28kW (no MMU support -- no RL support either,
though). 

32 kW for RT?  Wow.  Early on it didn't need anywhere near that much;
V2-SJ runs perfectly well in 8 kW.

DOS (earlier versions anyway) can run in 4 kW.
