Something you buy from IBM? ;-) 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)
