Well, read and learn.
We need to be running the S/370 hardware (twobob already fixed the config file in the post attachment above).
Then:
We should install (and run) VM/370 release 6
Which, can then run one or more instances of both MVS and DOS and even throw in an instance of a Linux/S-360 distribution.
(VM/370 was a landmark OS - the "VirtualBox" of the mainframe world. And it runs in 16Mbyte of ram. These are '70s operating systems, where "RAM" was hand sown cores per bit.)
Since the Kindle only has a "single window (at a time)" display system, and Hercules uses TCP/IP to 'talk' to its multiple consoles devices - -
We will have to play around a bit with the Kindle networking stuff.
More, tomorrow, unless we lose interest.

or I get lost in the choices:

well if it can be done on a Raspberry PI, then we will do it on a Kindle!
