z/VOS has not been released and no technical specifications are available.
It should not surprise anyone that this could and would be done. It's much
closer to detective work than rocket science. Once you acknowledge that the
x86 instruction set is a jungle when compared to the well ordered garden to
which most of us are accustomed, building the instruction support is tedious
but straight forward.
The challenge is not getting this to work; it's getting it to work well.
