In its current state, this computer is just as vulnerable to Van Eck phreaking as it was before Randy started up X. Before it was white letters on a black background. Now it’s black on beige. The letters are a little smaller and they live in windows, but it makes no difference: the electronics inside his computer still have to make these transitions between zero and one, i.e. between high intensity (white or beige) and minimal (black) as they trace out these patterns of dots on the screen.
