Does it really help? What does it cost to build a trustworthy emulator for an ancient system that you don't own the source for? What would it cost to just migrate your legacy applications to a newer mainframe that IBM supports?

I wasnt suggesting writing an emulator from scratch. I was suggesting emulating the mainframe. Here is what we, specifically, were looking at: https://en.wikipedia.org/wiki/Hercules_%28emulator%29 https://en.wikipedia.org/wiki/Hercules_%28emulator%29

  Don't you then need to pay IBM for the OS anyway? Will they license the OS for this use? Or did your system actually include the OS source?

    For 360, it is now in the public domain: https://en.wikipedia.org/wiki/OS/360_and_successors https://en.wikipedia.org/wiki/OS/360_and_successors
