The UNIVAC 1050 was a
Like the IBM 1401, the 1050 was commonly used as an off-line peripheral controller in many installations of both large "scientific computers and large "business computers". In these installations the big computer (e.g., a UNIVAC III) did all of its input-output on magnetic tapes and the 1050 was used to format input data from other peripherals (e.g., punched card readers) on the tapes and transfer output data from the tapes to other peripherals (e.g., punched card punches or the line printer).
A version used by the U.S. Air Force, the U1050-II real-time system, had some extra peripherals. The most significant of these was the
Subsequently, UNIVAC released the 1050 Model III (1050-III) and 1050 Model IV (1050-IV) for general purpose Commercial usage. The key difference between the two models was that of performance and expandability. The 1050-IV could be expanded to 64K of character addressable memory which could be accessed at two characters at a time with a cycle time of 2 microseconds per access (vs. 4.5 Microseconds in the 1050-III). Both models supported Decimal Multiply/Divide as an upgrade option.[1]
