You can give some characteristics that might qualify a given hunk of
iron as having mainframe status, but there will always be an
exception.
If it requires special cooling (e.g. chilled water, liquid nitrogen),
it's probably a mainframe.
If its DC power is derived from the output of an MG set, it's
probably a mainframe.
If it contains over a ton of wire, it's probably a mainframe.
