Introduction to generating and running OS/360 on Hercules

This is an introduction to getting IBM’s OS/360 operating system loaded and running on the Hercules emulator for the System/370, ESA/390, and z/Architecture systems. It assumes you have some familiarity with the 370, and with OS; in particular, you need to have some understanding of JCL, and of OS/360 (or later versions, like MVS or OS/390) usage and operation. It does not purport to be an introduction to the world of the 370.

This is a bit more complicated to set up than just about any other emulator or VM out there. A great weekend project for people with the right skill set and inclination.
