z/OS使用以下基本组件：
Hercules is an open-source software implementation of the IBM mainframe System/370, System/390, and z/Architecture. It enables you to run IBM operating systems like OS/390, z/OS, Linux for System z, and VM/ESA on non-mainframe hardware, such as a standard desktop or laptop.
Your downloaded ADCD package will contain a set of files, each representing an emulated mainframe DASD (Direct Access Storage Device) volume. These files are often in a compressed format called CCKD (Compressed CKD). Ensure you have enough free space, as a full z/OS 2.1 system can require tens of gigabytes.

Do not waste hours searching for a magical download link. Instead, spend that time compiling Hercules from source and setting up a legal, public-domain MVS system. You will learn more about mainframes in one hour of configuration than you will in a week of hunting dead links. hercules z os 21 download link
You can legally download an Ubuntu s390x ISO and install it inside Hercules to experience a 64-bit z/Architecture environment.
To build your mainframe laboratory, you should start by downloading the latest, most active fork of the emulator, known as . Official Download Sources:

Running z/OS 2.1 on Hercules is a rewarding project for understanding how mainframes operate. While a simple "download link" does not exist due to licensing, the provides the most appropriate route for access. Once set up, Hercules provides an accurate, efficient environment for exploring the power of z/Architecture. These files are often in a compressed format
Install the latest version of Hercules for your operating system.
To run on the Hercules emulator , you must obtain two separate components: the emulator software and the z/OS operating system images. 1. Download the Hercules Emulator
