    • Proposal for Reducing the Number of Tubes Used in Driving a Magnetic Matrix Switch 

      Mitchell, J. L.; DiNolfo, R. S. (MIT Digital Computer Laboratory, 1953-06-17)
      There are two independent questions that must be answered when choosing a switch operating mode: 1. Should the "set" and "reset" windings take part in the selection operation? 2. Should the "bias" drivers be gated? The ...

    • Proposal for Reducing the Number of Tubes Used in Driving a Magnetic Matrix Switch 

      Raffel, J. (MIT Digital Computer Laboratory, 1953-07-09)
      A scheme is outlined which eliminates roughly half the bias drivers used in present models of the magnetic matrix switch. It calls for an increase of about 50% in the number of wires passing through a core in the switch.

    • Proposal: Wiring and Construction Practice Specifications for Joint IBM-MIT Use 

      Watt, C. W. (MIT Digital Computer Laboratory, 1953-06-05)
      A meeting of the Joint IBM-MIT Standards Committee on Materials and Processes, held June 4 at M.I.T., agreed on certain soldering and wiring methods. The area of agreement was wide, and the following text outlines what was ...

    • Proposed Changes in FSQ-7 Memory 

      Shansky, David (Lincoln Laboratory - Division 6, 1954-07-13)
      A significant reduction of the cathode count coupled with an increase in operating speed of the FSQ-7 Memory banks can be achieved by a redesign of some of the sections of Memory. In order of increasing difficulty these ...

      Rich, E. S. (MIT Servomechanisms Laboratory, 1948-09-09)
      Memorandum from project Whirlwind research teams on a proposed five-digit multiplier marginal-checking installation.

    • Proposed Memory Address Selection System 

      Shansky, David (Lincoln Laboratory - Division 6, 1954-05-26)
      Increased memory in the use of cathodes is made possible by multi-level memory address selection and improved circuit designs.

    • A Proposed Readout Scheme 

      Fine, S. (MIT Digital Computer Laboratory, 1953-05-18)
      A good deal of delta and air-flux noise cancellation can be attained during readout by using the dФ/dt produced during the fall time of the read gate to cancel that produced during the rise time.
