1.8 Legal Advice

Hercules implements only the raw S/370, ESA/390, and z/Architecture instruction set, it does not provide
any operating system facilities. This means that you need to provide an operating system or standalone
program which Hercules can load from an emulated disk or tape device. You will have to write the opera-
ting system or standalone program yourself unless you possess a license from IBM to run one of their
operating systems on your PC or use IBM programs and operating systems which have been placed in
the public domain.

NOTE: It is YOUR responsibility to comply with the terms of the license for the operating system
you intend to run on the Hercules Emulator.
