Sweet. What changes to Hercules have you been considering? I have had a long running (and maintained!) MVS instance in Hercules for quite a few years now, just for fun.

I want a telnet port connecting directly to the Hercules console when it runs headless, as that is the way it ends up running in Docker. The Hercules console does a lot of heavy lifting that could be implemented at the terminal (as even Windows now has a proper terminal). It went as far as allowing me to connect and see the console transcript, which is pretty already.

Another thing I want that I haven't figured out is to print to my network printers - they all do lpr and ipp, but Hercules direct to socket approach didn't work for me and I need to do more research on that. Ideally, the line in the config could be a pipe command where I could turn the page into PostScript to be netcat it to the printer. or massage it through a converter that took in an IBM line printer EBCDIC stream and spat out ASCII for a "normal" printer.
