Erich Bloch, Who Helped Develop IBM Mainframe, Dies At 91 (google.com) 40

shadowknot writes: The New York Times is reporting (Warning: may be paywalled; alternate source) that Erich Bloch who helped to develop the IBM Mainframe has died at the age of 91 as a result of complications from Alzheimer's disease. From the article: "In the 1950s, he developed the first ferrite-core memory storage units to be used in computers commercially and worked on the IBM 7030, known as Stretch, the first transistorized supercomputer. 'Asked what job each of us had, my answer was very simple and very direct,' Mr. Bloch said in 2002. 'Getting that sucker working.' Mr. Bloch's role was to oversee the development of Solid Logic Technology -- half-inch ceramic modules for the microelectronic circuitry that provided the System/360 with superior power, speed and memory, all of which would become fundamental to computing."

    Farewell Erich Bloch, thanks for all your wonderful work but especially thanks for making my first job possible! (operations on IBM 3082 mainframes)

      Maybe a 3081 (dyadic), 3083 (uniprocessor), or 3084 (quad), but not a 3082. 3082 was the Maintenance Support Facility for the above machines. And 3087 was the coolant distribution unit, and 3089 was the motor-generator to create the 400Hz power.

    In those days, among the company's other great attributes, the company didn't get involved in politics.

    In today's IBM, the CEO just sent Lord Trump a feel-good letter about how to make profits together. At least one employee resigned over it.

    The URLs are easily searchable, but I submitted it as a story, so maybe it will come up later? I gotta run now.

    He suffered a refresh circuitry failure.

      Ferrite memory doesn't need refresh - it even holds its data over a power off.
      Trouble is reads are destructive - you have to re-write after reading.

        But ferrite core memory does not survive the panel being not-quite-gently-enough shut during operation, as I discovered when giving a computer room tour in the early 80's.
