Good morning I would like to know where do I download the emulator MainFrame Z/OS for Cobol

There are two possibilities.

• Hercules. It must be clearly understood: Hercules emulates the z/Architecture hardware. After you install Hercules you must obtain and install an operating system that can operate the z/Architecture hardware. Essentially all modern operating system such as z/OS are copyrighted by IBM and cannot legally run on your PC. It is relatively easy to obtain pirated copies of z/OS, but only an early version of MVS can legally run on Hercules. After you have installed the operating system you must obtain and install the Cobol compiler. Fandezhi uses Hercules.
• z390. z390 is another emulator, though less comprehensive than Hercules. Google z390 Cobol. and you will come up with http://www.z390.org/zcobol/. I suspect it is less difficult to install than Hercules and a pirated version of z/OS.

So first I need to install another operating system? What do I download?
After I download the emulator that is this link that you sent me? so I tried to come in here and it did not work.
I really like cobol, so that I find very difficult to get the materials and programs. I need help.

The Download link is here http://www.z390.org/
