USE OF UMC TYPE DIGITAL COMPUTERS FOR GEODETIC COMPUTATIONS (ISPOLZOVANIE ELEKTRONNYKH TSIFROVYKH VYCHISLITELNYKH MASHIN TIPA UMC DLYA GEODEZICHESKIKH VYCHISLENII),

Abstract

The article discusses the compatibility and effectiveness of two types of computers used by the Polish Geodetic Service. The UMC-1 is a small, electron tube, fixed point computer with an access time of the order of 100 operations a second and a magnetic drum memory of 4096 34-bit words; input and output are from punched tape and teletype. The UMC-10 is a transistorized, fixed point computer with speeds of 2000 operations per second, internal ferrite memory of 4096 34-bit words, supplementary external magnetic drum memory, punched-tape readers (500 characters per second), punched tape and teletype input and output (150 characters per second). Both types of computers possess identical logical structure and use the same system of coding.
