<p>Teleprinter input units such as a receiver EM, a keyboard TA, a punched tape reader LE and a message store NS1 are connected via a single data bus DB to output units such as a transmitter SE, a printer DR, a tape punch LO and a message store NS2. Connection paths between the input units and output units are provided via respective buffer stores P1 to P3 which are selectively operated in an appropriate sequence to enable simultaneous data transfer between more than one input unit and more than one output unit via more than one connection path. The buffer stores may form parts of a unitary store DS which may also include the message stores and a working store AS. Data transfer is controlled by means of a micro-computer MR. <IMAGE></p> |
