z/OS on a PC

Have you ever hoped to try your hand on an operating system designed for an big iron computer?

For example, z/OS?

The problem is that nobody has the hardware at home to ride such a monster.

As it takes, here’s how to run z/OS in the hercules emulator for PC.

Configuration

A key element to run Z/OS on Hercules is the hercules configuration file.

This file informs, amongst other things, the location of DASD files.

To illustrate this, assume that the DASD files are in /hercules/cckd.

We will then inform the hercules.cnf file in the following way:

# DASD Devices

0A81 3390 cckd/zares1.cckd sf=shadow/zares1_*
…
0A9A 3390 cckd/sares1.cckd sf=shadow/sares1_*
