This is silly. Broken computers don't give wrong answers. They crash,
or they log soft errors, or they act flaky. It is almost impossible to
imagine a hardware fault that would have no visible effect other than
to make the 'value' (whatever it may be) of the output wrong.

Of course, floating point hardware is a little different, since it
is used only for numerical calculations which are part of the problem
( as opposed to the CPU alu which is also used for indexing, etc.)
You can always arrange to run an FPU diagnostic every 5 mins if this
is an issue.

There are few things more useless than a computer that executes
instructions correctly 999 times out of 1000....
