Interesting in contributing, but no longer work on a z/OS system.

I'm pretty sure this is hopeless, but I just retired and am interested in contributing, but no longer have access to a z/OS system. As far as I am aware there are no free (or almost free) z/OS systems available for this sort of thing. But perhaps someone knows of one.

I haven't tried this so YMMV
