Abstract
(EN)
An electronic device for memorizing and recalling key stroke sequences is connectable between a computer and its keyboard. The device has a microprocessor (17) controlling memorization of the sequences in a memory (18) at addresses specified via a key pad (1). The microprocessor is connected by two monitor and drive circuits (21, 22) to the clock and data lines (4c, 4d, 3c, 3d), between the computer and its keyboard. Between these circuits is a switch (23) for disconnecting the keyboard during transmission of a memorized keystroke sequence.

Appareil électronique permettant de mémoriser et de rappeler des séquences de frappe que l'on peut connecter entre un ordinateur et le clavier. L'appareil contient un microprocesseur (17) qui gère la mémorisation des séquences dans une mémoire (18) à des adresses spécifiées par un clavier numérique (1). Le microprocesseur est relié à la ligne de signaux d'horloge et la ligne de données (4c, 4d, 3c, 3d) au moyen de deux circuits de contrôle et de commande (21, 22), placés entre l'ordinateur et le clavier. Entre les circuits se trouve un commutateur (23) qui permet de déconnecter le clavier pendant que la séquence de frappe qui a été mémorisée est transmise.
