Abstract

In a personal computer system, the omnipresent keyboard connection (201) is 'souped up' by applying to the connection a known high-speed multiplexed serial connection protocol (203). Peripheral devices (213, 215, 217, 221, 223) are then incorporated into the keyboard, thereby minimizing cable and desktop clutter while providing a full feature set. Examples of peripheral devices that may be included in the keyboard include a PC CardTM or Card BusTM slot (213), a smart card read/write unit (215), speakers (221), microphones (223), etc. Consumers may thereby be afforded a greater degree of choice, since keyboard models are generally easier than computer models to make, ship, and inventory.
