    Abstract: Michael Allen Wingfield, former UCLA engineering graduate student, was part of a team responsible for installing the Interface Message Processor (IMP) and creating the first Advanced Research Projects Agency Network (ARPANET) node at the University of California, Los Angeles. He designed the hardware interface linking the Scientific Data Systems (SDS) Sigma 7 computer at UCLA with an IMP to connect to the ARPANET in 1969, making UCLA the first site to receive an IMP. He also implemented Transmission Control Protocol/Internet Protocol (TCP/IP) for Unix, a family of multiuser computer operating systems, in 1979. His papers detail the design specifications of the IMP for ARPANET and the TCP/IP source code for UNIX, and include: handwritten notes, manuals, specifications, computer printouts, and photographs.

    In June of 1969, Michael Allen Wingfield, an engineering graduate student, was asked by Steve Crocker at UCLA to design the hardware interface between the Scientific Data Systems (SDS) Sigma 7 computer and an Interface Message Processor (IMP) from Bolt, Beranek and Newman (BBN) to connect the UCLA system as the first node on the Advanced Research Projects Agency Network (ARPANET), the precursor to the internet. After reviewing the BBN 1822 IMP interface specification, Wingfield drew up flow charts, logic diagrams, and a test program for the IMP when it was received from BBN in September 1969.
    The ARPANET, now the internet, was born on August 30, 1969 when BBN delivered the first IMP to Professor Leonard Kleinrock's Network Measurements Center, a role to which UCLA was assigned as one of the first four sites of the ARPANET to provide either network support services or unique resources. Kleinrock and his students, including Crocker, were deeply involved in the development of techniques to monitor the ARPANET's early performance. Their presence made it natural that UCLA obtained the first node on the ARPANET.
    In 1976, Wingfield was hired by BBN, and in 1979, he went on to become a project manager with the National Bureau of Standards to provide a three-node network and the latest protocols. During this time, Vint Cerf, Jon Postel, and others were developing the Transmission Control Protocol/Internet Protocol (TCP/IP) to replace the Network Control Protocol (NCP) in order to better span interconnected networks. When the TCP4 protocol was specified, Wingfield implemented TCP/IP on a UNIX computer using the C programming language.

    Scope and Content

    The Michael Allen Wingfield papers include handwritten notes, manuals, guides, booklets, photographs which detail the design of the Interface Message Processor (IMP), and computer printouts which include the source code for Transmission Control Protocol/Internet Protocol (TCP/IP) that Wingfield wrote for UNIX.

    Organization and Arrangement

    The collection is arranged into the following series:
    • Series 1: Interface Message Processor (IMP)-Host Interface Specifications
    • Series 2: ARPANET Manuals and Workbooks
    • Series 3: Source Code for TCP/IP for UNIX
    Within Series 2, manuals and documents are arranged chronologically. Within Series 3, the computer code was kept in its existing order to reflect the program design.
