Abstract
The apparatus comprises an electronic teleprinter constituted by a first set of basic peripheral units such as the printer, keyboard etc. as well as a punch/reader, arranged to converse directly with the line and controlled by a first central unit, and a second set of peripheral units such as a disc unit, one line display and VDU controlled by a second CPU and able to execute more sophisticated operations such as the automatic filing of messages, their display etc. The two CPUs each autonomously control their own peripheral units with simultaneous processing, and periodically communicate with each other for the exchange of data and commands by way of an interface in an auxiliary unit. The CPU of the basic machine is thus free to handle the basic input/output procedures without having to service the auxiliary peripherals.
