A bit of character ....
As you type at your 6128 keyboard, you should not take for granted the fact that
recognisable letters and numbers etc, appear on the screen. After all, we've already
discussed the fact that your computer is not a typewriter. What's actually happening
is a result of you pressing a combination of electrical switches. The electrical signals
produced when you press these switches are translated by the circuitry inside the
equipment to produce a pattern of dots on the screen. We recognise that pattern of
dots as a letter, number, or other character from the 6128's 'character set'.
