Perhaps I did not accurately read the introductory post for this topic, but if we are considering 360 and its descendants, I am surprised no one has mentioned either SVS or VS1 (though I did see where MVS was mentioned). One of my first jobs out of college (70s) involved a conversion from SVS to VS2. A later job involved bringing a site from VS1 to MVS/370.
