The IBM Z mainframes seem really neat. I don't have a use case for using one of course, but I wish IBM had like a weak virtual system for training that was open for the public to play with.

Z Xplore at least used to include Z series access.

I didn't know about this! Is it truly free of charge? Seems too good to be true.

Haven't used it for a couple of years, but I think it's still a free login ID with 1-year validity. You can re-apply every year.
