That is correct (except that it was HP's 825!).

I think my last posting should have cleared up the
confusion.  Again, sorry for the problems.  But for HP to answer:
shouldn't the 825 gone through some sort of check at boot time and
told us if something was wrong?  The 825 math seems to be about 3x
faster than a single cpu 500 for problems involving normal math + -
/ *) on arrays.
