| The IBM 1130 computing system was designed for on-the-job problem solving by engineers, scientists and business people. A portable information storage device, the IBM 2315 disk cartridge (foreground), enabled users to maintain their own programs and data on individual disks. Disks could be inserted, as shown, in the computer for immediate processing when needed. This 1130 could perform computations at the rate of 120,000 additions a second. |
