Bet many were 30 year old 4381s, 3081s or whatever running MVS prior to XA. Depends who you ask. Application base code may not have changed much. I'd hope front-ends are no longer subarea SNA!
Many hardware and software upgrades later we have modernised the mainframe. Didn't MVS address spaces invent the 'Cloud'? For what mainframes do well, try doing it better AND cheaper in the 'Cloud'. Same as the 30-50 year old spade with 3 new blades and 10 new handles.

Sixty-four percent are running mainframes between 10 and 20 years old, with 28% running machines that are 20 to 30 years old. " So 2/7 are running machines over 20+ years old? And 2/3 over 10 years? What does that even mean? Smells fishy to me. What is the sample size? Is it biased somehow?
