A special adapter unit has been developed for connecting accessory components to a shipboard computer. The unit is used to control auxiliary external memory. Structurally, this adaptor consists of the following 1 a control unit for a PL-20 tape puncher, 2 units for controlling the card puncher and 3 punchcard input units. The PL-20 puncher encodes in the selected mode on paper tape at a rate of 20 characters per second. The card-punch control unit is used to perforate numerical information coming from the computer. The punchcard input unit provides code conversion in the form of potentials, in a pulsed 26-digit code, and storage in the computers operative memory by a given address. It is noted that the Dnepr-1 computer and the accessory components are completely suitable for modification and development into a shipboard computer center. An evaluation of the operating reliability of the computer system is given.
