And parity isn't even all that good for detecting errors. Worse, what do you
do if you detect a parity error on a RAM location? You have no correction code
with parity -- you need Hamming or some other ECC code for that.

So with the parity situation, we have a system that's intrinsically not all
that good, and then we compound the problem by not fully implementing it, as
Phil points out.

I wonder if that would impact reliability?
