the typewriter-keyboard conversion
This little how-to, complete with circuit board layout and lots of photos, describes the conversion of an old Smith-Corona manual typewriter into a computer keyboard.

[S]he finds old-fashioned mechanical typewriters much easier on her fingers because they offer gradual resistance rather than the feeling of moving through air then hitting a wall, like most computer keyboards."
