Fun things to do with your VM/370 CE machine – Fun with big computers

VM/370 Community Edition is an improved version of IBM's last freely-licensable mainframe operating system, offering modern features comparable to contemporary Linux distributions. Users can easily run it through Docker containers, or alternatively access it through actual IBM mainframes if their organization permits, though physical machines are impractical and expensive for hobbyists. The Community Edition runs only open-source or public-domain software and operates within the constraints of a single CPU and 16MB of memory.
