OK, now I understand. Dave Bond wrote the old Tachyon Assembler Workbench,
a similar emulator for batch problem state z/OS programs...

They certainly won't bless it, but if what I have gleaned is correct it 
basically performs a similar task to the Z390 product.

http://www.z390.org/

so executing the problem state code and emulating the interfaces and API's. Of 
course some of the API's and problem state code may be 
protected by Patents or Copyright. Copyright violations can perhaps be 
minimized by a clean room approach, and patents perhaps by choosing a suitable 
country..
So as long as they don't sell the code elsewhere then IBM might have to 
challenge them in a Swiss court:-

https://en.wikipedia.org/wiki/Software_patents_under_the_European_Patent_Convention

which might be less in favour of a US corporation...

.. but of course, I am only musing aloud, and we will have to wait to see 
actually happens. I guess if they never land a sale then nothing will happen...
.. if they I expect things to get interesting...

​I'm speculating that it is a hybrid. A fast glance said it runs z/OS
executables. But I'll bet they mean only those which use proble​m state,
but not supervisor state, instructions. When the program does something
like an SVC or PC, I'll bet that some sort of native code routine which
implements the standard z/OS API function runs; unlike Hercules/390. I.e.
the API function "marshalls" the z/OS API data; invokes the needed host OS
 functions; then "unmarshalling" the results back to the application. A bit
like Wine does for the Windows API under Linux, but with instruction
emulation thrown in. Say, as if you could run Wine on Linux/ARM with QEMU
emulating the x86 instructions.

Yet another emulator...IBM will not bless this, will they?

Haha! That superscripted 'z' didn't quite work in plain text. Anyway,
