Maybe, the best contemporary definition is "a

would preclude such Hitachi systems that actually run on Xeon CPUs and
emulate the z Architecture, but I'm sure some wordsmithing could fix that
while keeping things like Hercules emulator from falling into the
definition's space.
I see that Unisys is moving their machinery over to using Xeon CPUs. What
does that make the new Unisys machines?
