FYI Unisys also makes available free emulators of their two mainframe environments. The ex-Burroughs MCP IMHO is a lot more interesting than the yucky IBM stuff

  I tried, but without good tutorials, it's incredibly hostile. I can understand why Bonnie McBird named Tron's villain after it. Her husband, Alan Kay, was at Unisys back then.

  Indeed, ClearPath is one of the few surviving OSes written in a (almost) memory safe system programming language, 10 years older than C. Sadly most people don't get exposed to these kind of platforms and think that until 1973 everyone was doing Assembly only OSes and then came C out of nowhere.

  Do you happen to have a link to it? I've been playing with MVS 3.8j on Hercules on and off for the last year and found it rather interesting. I'd love to play around with the Unisys stuff as well, since I've never used it before.

    I went looking for it myself a while back: https://www.unisys.com/offerings/clearpath-forward/clearpath-forward-products/clearpath-mcp-software/clearpath-mcp-express https://www.unisys.com/offerings/clearpath-forward/clearpath... Unfortunately, I haven't got access to a Windows machine at the moment.
