| | IBM 1620 Model I - Wikipedia, the free encyclopedia |
 | | The IBM 1620 Model I was the original implementation of the IBM 1620 scientific computer, introduced in 1959. | | | One industry magazine (Datamation) mentioned that the 1620 was the first IBM computer for which the basic system could be leased for a monthly rate less than its number. | | | Expansion to either 40,000 or 60,000 decimal digits required the addition of an IBM 1623 Memory unit. |

| | IBM 1620 - Wikipedia, the free encyclopedia |
| | The IBM 1620 was announced by IBM on October 21, 1959 and marketed as an inexpensive "scientific computer". | | | Although the IBM 1620's architecture was very popular in the scientific and engineering community, computer scientist Edsger Dijkstra pointed out several flaws in its design in EWD37, "A review of the IBM 1620 data processing system" (see http://www.cs.utexas.edu/users/EWD/index00xx.html at the Dijkstra archive at the University of Texas). | | | Following announcement of the IBM 1620 on October 22, 1959, due to an internal reorganization of IBM, it was decided to transfer the computer from the Data Processing Division at Poughkeepsie (large scale mainframe computers only) to the General Products Division at San Jose (small computers and support products only) for manufacturing. |

| | The IBM 1620 was a general-purpose, stored-program data processing system for small businesses, research and engineering departments of large companies, and schools requiring solutions to complex problems in the areas of engineering, research, and management science. | | | A subset of the 1620 SPS, this system required only one pass of the source program tape to assemble and punch out an object program. | | | Additional FORTRAN language statements were included, and high degrees of precision in computation could be achieved by specifying the length of number fields in excess of the fixed length normally allowed. |
