IBM 7090 Tape Drive, LLNL, 1960s

Lawrence Livermore National Laboratory computer operator Bob Rose changes a magnetic tape on the IBM 7090 in the Livermore Computer Center. No photographer credited, dated August 1960. The IBM 7090 was a second-generation transistorized version of the earlier IBM 709 vacuum tube mainframe computers and was designed for "large-scale scientific and technological applications". The 7090 was the third member of the IBM 700/7000 series scientific computers. The IBM 7090 was a second-generation transistorized version of the earlier IBM 709 vacuum tube mainframe computers and was designed for "large-scale scientific and technological applications". The 7090 was the third member of the IBM 700/7000 series scientific computers. The first 7090 installation was in November 1959. The 7090 used a 36-bit word length, with an address-space of 32K (32,768) words. It operated with a basic memory cycle of 2.18 ?s, using the IBM 7302 Core Storage core memory technology from the IBM 7030 (Stretch) project. With a processing speed of around 100 Kflop/s, the 7090 was six times faster than the 709, and could be rented for half the price. No photographer credited, circa 1960s.
