   I can't think of any now for which that would be true.  Maybe   
   DOS/VS or something?   
      
   The idea of a PC operating system on a mainframe is silly.  A   
   single-tasking, unprotected, glorified program loader like DOS   
   that provided synchronous, programmed IO would be hopelessly   
   inefficient for a heavy-use mainframe.  It's one thing on a   
   cheap 8- or 16-bit micro where you don't care about wasting   
   cycles while the user thinks about what to type next.  Quite   
   another on your big compute engine when you want to keep the   
   CPUs and IO devices running as close to capacity as you can, to   
   maximize the return on your multi-million dollar hardware   
   investment.
