not dumb at all.  the lightguide we're talking about is the plastic
piece sandwiched between the screen and the white plastic bezel that
surrounds the screen.  if you look at the thin edge that's visible,
it will either be dark, basically black, or transparent -- you'll be
able to see bright reflections from surfaces within it.

most B1 machines have the clear variety, but some number were modified
to have the dark lightguide (which is actually a very dark red) before
being sent out to users.
