What does HackerNews think of hyperion?

>No free developer OS distributions or licenses, (so no way to run them on an emulator), no freely available emulators for modern hardware & OS releases, nothing.

Distro:

https://wotho.ethz.ch/tk4-/

Update to Distro:

http://www.prince-webdesign.nl/index.php/software/update-on-...

Emulator:

https://github.com/SDL-Hercules-390/hyperion

It's a MVS TK4- distribution and probably 99% of a z/OS functionality plus it's Public Domain.

Or VM/370 another Public Domain OS from IBM:

http://www.vm370.org/vm

Or even better you run MVS TK4- inside VM/370...for the real taste ;)

But if you really really want z/OS (i have no clue why you would do that) you click here:

https://www.ibm.com/it-infrastructure/z/education/zxplore

(Formerly know as Master the Mainframe)

And some yt's to have a little base-knowledge (mostly MVS and VM/370):

Extract and run MVS 3.8j TK4- [1] on Hyperion [2] is a bit...hmm less time consuming then installing a barebone MVS, plus more tools, games, compilers...and basic tcp ;)

And a pretty good youtube channel "mostly" dedicated to MVS and other mainframe os's

Still actively maintained:

https://github.com/SDL-Hercules-390/hyperion

And it runs on MacOS

>Is it technically possible to run z/OS

Yes but not legal checkout MVS Tur(n)key:

http://wotho.ethz.ch/tk4-/

And run it with the new Hercules emulator:

https://github.com/SDL-Hercules-390/hyperion

MVS is near identical to z/OS and the Turnkey Distro has much more compilers and tools..and games already installed.
