The quote I heard attributed to Seymour Cray had to do with the use of
parity bits in the old CDC6600 memory subsystem.  Supposedly Cray
dismissed the idea out of hand, saying:

	Parity is for farmers.

Well, at least that's the way I heard it.

By the way, this came to haunt us when I was in graduate school.  We
had a CDC6400 (sort of a poor man's 6600), and one of the data lines
between the periperal processors and main memory went on the fritz.  It
was VERY difficult to isolate.
