Abstract : The UP-1 digital-analog converter is intended for coordinating the operation of the M-20 digital computer with various analog computers. Substitution of the Dnepr-1 computer for the M-20 involved solution of the following problems: (1) as the Dnepr-1 delivers negative 7-v pulses while the Up-1 requires positive 40-50-v pulses, some circuits and assemblies in the Up-1 were altered; (2) special instructions were worked out for feeding digital information into the UP-1 and for taking it out; a simultaneous exchange of information would require 45 binary digits; only 26 digits were available in the Dnepr-1; 3) definitely space pulses are required for access to the UP-1; hence, such pulses had to be designated from those available in the Dnepr-1. Changes in schematics are shown.
