The original text does not have "the Harvard" or even "the".  This is one
of the amusing and endearing aspects of the text: The computer in use was
often (though not consistently) referred to as just "Mark IV" (as if it's a
living being?).  I imagine that's a sentiment that can arise when
"conditions were far from ideal" and "the reliability ... has now been
greatly improved" to "operating with more than 85% good running time".
