They do have a binary backward compatibility date sometime in the 1960s, possibly 1964.
But from what little I remember from my intro-to-mainframes day at big blue many years ago, I think it's like some sort of multi-layered emulation now, to run code that's that old. But your "Hello World" program built on OS/360 released in 1964 will still run on modern Z/OS, or so I'm told.
Of course they're not desktop systems! (I'd hate to see the desk...)
