- 360_Model_20 abstract "The IBM System/360 Model 20 was the smallest member of the IBM System/360 family announced in November, 1964. The Model 20 supported only a subset of the System/360 instruction set, with binary numbers limited to 16 bits and no floating point. In later years it would have been classified as a 16-bit minicomputer rather than a mainframe, but the term "minicomputer" was not current, and in any case IBM wanted to emphasize the compatibility of the Model 20 rather than its differences.Developed by IBM in Böblingen, Germany, the system was intended for data processing and as a replacement for tab equipment. An incompatible small computer, the IBM 1130 introduced the following year, was designed for scientific and engineering computing.The design of the Model 20 was the result of a tug of war within IBM. John Haanastra had wanted a low-end machine that could execute IBM 1401 instructions. Fred Brooks wanted the machine to have System/360 architecture. The final result was a compromise where cost concerns predominated: the system leased for under $2000 per month including MFCM and line printer, compared to around $3000 for a comparable 1401.Based on number of systems sold the Model 20 was the most successful model of System/360. According to Pugh "The number of Model 20 processors installed by the end of 1970 in the United States exceded 7,400." Other models, however, brought in greater revenue.".
