    • The Incorporation of a Magnetic Matrix Switch into a Multiplanar Coincident-Current Magnetic Memory 

      Hughes, A. D. (MIT Department of Electrical Engineering, 1953-11-12)
      Master's Thesis Research Proposal on the Incorporation of a Magnetic Matrix Switch into a Multiplanar Coincident-Current Magnetic Memory. The purpose of this thesis is to investigate the problem of driving a large (64 x ...

    • New Metallic Cores from Magnetic Metals 

      Hughes, A. D. (MIT Digital Computer Laboratory, 1953-01-02)
      A preliminary test on 12, 1/4-mil molybdenum permalloy cores from Magnetic Metals indicates that signal ratios are unsatisfactory for memory application. Disturbed-one-to-disturbed-tero ratio is about 35; disturbed-one-t ...

    • Testing of Individual Cores in MTC Memory Planes 

      Hughes, A. D. (MIT Digital Computer Laboratory, 1953-06-16)
      The 32 x 32 magnetic-core memory planes for MTC were constructed from cores tested and sorted on a production basis. To obviate the possibility of defective cores, each core was retested after it had been wired into a ...
