Data memory card (11) for work-station computer for connecting system

摘要

The data memory is a card (11) with an interface (12), a CPU (13) connected by a bus line (16) to a first memory (14) for storing general and user data, and to a second memory (15) for storing data referring to a comparison process to obtain data agreement. The computer is connected by the interface (17) with the data input section (18) for the input of comparison data. The interface (17) has a data managing unit and an amplifier for supplying signals of sufficient output power. Signals can be exchanged with a workstation computer equipped with suitable interface.
