Look at ENQ for an example of changes that affected all three.
Somewhere along the line the concept of automatically relocating code
was put out of its misery. The original MPS was very different from
MVT.

Essentially MVT without regions.

We had an SE in the mid 1970's who claimed that IBM was ready to ship
a TSS release with a virtual machine capability but pulled the plug on
it at the last minute. He claimed that performance was good, and was
not a happy camper when it was dropped. I don't know whether VM/XB was
based on that work or was done from scratch.
