Abstract

Système d'affichage de données pourvu d'une interface pour la connexion d'unités secondaires permettant d'étendre la capacité du système de façon modulaire. Le système comprend une unité de base ayant une interface 34 pour connexion à un contrôleur 10, un bus d'entrée et un bus de sortie 18 et des moyens pour effectuer des transmissions de données sur le bus 18 en réponse à l'état de l'unité de base, les entrées de données pouvant se faire soit par clavier 66 soit par le photostyle 70 et les données de sortie étant visualisées sur les dispositifs d'affichage 58, 60, 63 ou imprimées par l'imprimante 62. Un tel système présente une grande flexibilité et peut s'adapter aux besoins des utilisateurs.
