Pretty and seems to work otherwise. 

That's nothing... 
At the moment I have a KL10 and MVS S360 booting up under emulation, on oorexx.

I mentioned it before in another room, long lost to memory  but related, recently i learned python is supported on the IBM mainframes.   Was quite surprised, tho in hindsight i shouldn't have been.  

I still don't see why we have one. Its running ONE application now. That's it. And its not 'tied' to the mainframe, just no one will spend the $ to have a replacement made/bought.  I suspect millions a year to keep it going and supported.

Currently attempting building python3.13 and only hitting a snag with NaN floating points... I'm circumventing this by removing quiet NaNs from the build, and we'll see how fast that breaks when working with floating points HA HA...

 

 

This is real IBM hardware, no emulation going on.  With all its overhead.

Cool.  Bootstrapping either of those environments is no easy feat, even under emulation.

long ago i messed with Hercules Emulator..   from what i remember it was neat, tho it bought back some old memories of being in a basement at EDS on a green screen, late 80s, yelling at some JCL trying to get something to run.   COBOL was fine, JCL, sucks. ( or at least did )

But it helped me decide "this is not the career path for me" I quit the next week.
