  I kbnew you were making a funny.

   Yes, I agree.  And no matter how fast they get, that will always be
the case.   It is one of a great many corollaries to Finagle's Law. (for
examnple: my 100 Mhz logic analyzer design just doesn't seem to want to
fit into an AVR, dag nab it all to heck!)

   Now that one I hadn't heard about!   But then, I have always made it
a habit to attempt to ignore anything Intel related.
