Hercules does not come with MVS 3.8j, that just happens to be the version of MVS that is available publicly. You can also run several other mainframe operating systems on it.

More likely, the terminal locked up. If you try to type where there is no field to type into, you'll lock the keyboard. To reset it, press Escape, then tab to the field you want to type in.
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.
I can understand why Bonnie McBird named Tron's villain after it.
Her husband, Alan Kay, was at Unisys back then.
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.
Unfortunately, I haven't got access to a Windows machine at the moment.
I also setup a vm370 system with a few different things running on an older Raspberry PI. It was fun to think I could run the old application I maintained on a system that is about the size of the pack of cigarettes my old boss use to keep on his desk.
docker run -it -p 3270:3270 rbanffy/vm370
The idea of running a 1970s vintage operating system inside a Docker container amuses me. Old meets new. (For extra "old meets new", I should make it run under k8s.)
It's most likely a synchronous modem meant for 4 wire leased lines, which don't really exist anymore.
The other port is standard rs232.
People have such short attention spans and the judges kept making him start over repeatedly... and when they started booing I genuinely felt for the guy.. Props to the guy for keeping clear, that would have destroyed my spirit.
I remember exploring MTS back in the day, UBC was running it on some kind of machine in the mid-1970s.
