IBM 7040 Data Processing System

The IBM 7040 was a historic but short-lived model of transistor computer built in the 1960s. IBM 7040 memory (2 x 16Ko)It was announced by IBM in December 1961, but did not ship until April, 1963. A later member of the IBM 700/7000 series of scientific computers, it was a scaled down version of the IBM 7090. It was not fully compatible with the 7090. Some 7090 features, including index registers, character instructions and floating point, were extra-cost options. It also featured a different input/output architecture, based on the IBM 1414 data synchronizer, allowing more modern IBM peripherals to be used.
