Abstract : A new standard is extended here to punch-card and punch-tape input and output devices for general-purpose electronic computers. The notation, nomenclature and characteristics of these devices are specified, as are their principal parameters: technical rate of loading and extraction of information in start-stop and continuous regimes; capacity of the loading magazine and receiving pocket for the cards; technical rate of print-out for sequential alphanumeric printing, line-parallel alphanumeric printing, and line-parallel digital printing. Rules are given for the number of digits in a line, the spacing of print, and certain other print-out parameters. The GOST (All-Union State Standard) 10525-63 also specifies the digits and signs which should be used in input and output devices, on leaving to customers the right to set up their own combinations of the specified symbols and introduce new signs. The purpose of this standard is to establish the unification and interchangeability of input and output devices. Standards for 'Alphanumeric Codes for Punch Cards and Punch Tapes and Perforated Tapes. The Shapes, Basic Parameters, Sizes and Positions of Holes on a Punch Tape,' have been drafted and approved.
