I'm going to say something that runs a mainframe OS.
This includes IBM's zPDT & RDz which are software emulators. It also
includes a P/390-E, et al., card that has a physical S/390 processor.
I bet that Hercules qualifies here too. But that's an /emulated/ mainframe.
Much like zPDT & RDz.
How about the XT/370? or XT/360?
(I couldn't afford one)
