I don't understand lots of those things either, Ferret. But, on the subject of calculators, I remember when I first started work there was an old Olivetti mechanical calculator. The bigger the numbers the longer it took to chunk away to figure the answer. It got there. I remember it used to take 36 seconds to figure that it couldn't divide 999,999,999 by zero. Made a hell if a racket while it did it.
