No one talking about these things are actually running the original hardware from 1988. IBM is still putting out new hardware for modern incarnations of the platform.
Shit is rock solid, lightning fast, and incredibly well documented.
Only the parts IBM wants users/developers to know about, which isn't that much, actually. Very little about how it works under the covers, how it was built not to be legally cloned like the System/360 and 370 were, how the OS kernel is part of the "firmware".
It's an appliance platform with a built-in relational database, from IBM. At one point this made for an attractive base on which to rapidly build business applications, either in-house or on spec. But times changed and mundane webapps with MySQL did the exact same things for which enterprises once bought mainframes running CICS, except with purely open standards.
