Note that the PowerPC 604 processor does have parity protection for its
on chip cache. It (and the 603, too) even has parity protection not only
on its data bus, but also on its address bus, and it even honours it when
snooping the bus.
Too bad that the world seems to be through with the PowerPC :-(.
