I do not think Vojtech wants snail mail these days (and he mentioned that nobody has ever sent him snail mail), and the address is not even valid anymore, so let's remove snail-mail instructions from the sources.

|
|
* (the keyboard ACIA also handles the mouse and joystick data, and the keyboard
|
|
* interrupt is shared with the MIDI ACIA so MIDI data also get handled there).
|
|
* This driver only deals with handing key events off to the input layer.
