Here's an imperfect digital image of a 1991 IBM wall poster of "MVS/ESA
V4 System Flow" complete with IBM Document number (lower-left):

My recollection is that the original was 3' - 4' on a side.
The multiplicity of isolated user virtual address spaces which gave MVS
its name and strong inter-user protection properties is shown by stacked
"User Area"s and "Extended User Area"s, a diagram subtlety which would
likely be overlooked by someone who didn't understand the significance.
I remember seeing other MVS-OS/360-z/OS wall-poster structure diagrams,
but this seems to be the only one I bothered to preserve.
