>There has to be more in the OS space than Unixes and MVS-derived OSs
Haiku which comes from BeOS. I don't recall the linage of BeOS and the wikipedia entry is lacking but it is not Unix, anyone?

When I think of non-Unix and non-MVS i'm thinking more on the line of the IBM i, PalmOS, or the Newton OS. All three are quite alien under the hood to anyone who grew up on a Windows/Unix world.
The main _inspiration_ was the Amiga, but not really AmigaOS.
BeOS was built in the still-new C++ but AIUI predates a lot of standardisation of C++ which subsequently happened -- as was Psion's EPOC32 and its later rebranding as Symbian.
