2 Intelligent Keyboard (ikbd) Protocol
9 The Atari Corp. Intelligent Keyboard (ikbd) is a general purpose keyboard
10 controller that is flexible enough that it can be used in a variety of
11 products without modification. The keyboard, with its microcontroller,
12 provides a convenient connection point for a mouse and switch-type joysticks.
13 The ikbd processor also maintains a time-of-day clock with one second
18 The ikbd communicates with the main processor over a high speed bi-directional
20 different applications of the keyboard, joysticks, or mouse. Limited use of
21 the controller is possible in applications in which only a unidirectional
