Is 'MVS/ESA' worthy of a mention (or has it already featured?) '3.1.0e' (?) was my first taste of MVS. The cheapskate company involved tried to forego expanded storage on the machine. Did it do anything productive? Yes - but not in any useful timescale. We quickly came to the conclusion that 'ESA' meant 'Expanded Storage Assumed'.
