This site is dedicated to Historical Releases of the IBM VM/370 operating system. This consists of two main components:-
- the Control Program (CP), which was probably the first Hypervisor to be widely deployed,
- the Conversational Monitor System (CMS) a simple single user operating system
When the that user logged into a terminal CP would create a Virtual Machine into which the user would IPL CMS. The original system from IBM was very simple and has many shortcomings. However has been enhanced over several years by an enthusiastic group of programmers who have produced various releases of this code.
The latest incarnation has been titled "VM/370 Community Edition". Click the "VM/370" tab above the available releases.
