Abstract : Circuit schemes and subroutine programs are described for the computer 'Dnepr-1', which permit one to realize an interruption mode for effectively inputting new information arriving along telephone and telegraph communication channels. At the arrival of a signal, two machine states are possible: (a) computation in accordance with the main program, and (b) stop. Depending upon this condition two interruption modes are distinguished. A description is given of the operation of the circuit scheme and subroutine program which effect the input of information and the return to the principal program where it was interrupted. (Author)
