| | 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 Archives: 1620 Data Processing System |
| | 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. |

| | What was way cool about the Model 1 was that the math tables of the machine (yes, the IBM 1620 did math the old fashioned way, it looked up the answer) were stored in memory, so you could actually modify the tables to do arithmetic in any base less than 10. | | | I always thought that it was a nice touch that the hardware instruction that did a return on the console typewriter was the same instruction (with a different device specified) that did a seek on the hard disk. | | | (1) The 1969 Universal Pictures Movie "Colossus: The Forbin Project" used the IBM 1620 control panel as the front end of the Colossus super(duper) computer, which was encased in a mountain, surrounded by intensified gamma radiation, and placed in sole, irrefutable charge of the USA's national nuclear defense system... |
