Drawing on feminist tradi- tions of situated knowing, we designed an electronic quilt and a series of participatory workshops that materialize the work of the core memory weavers. With this case we not only broaden dominant stories of design, but we also reflect on the entanglement of predominantly male, high status labor with the ostensibly low-status work of women’s hands. By integrating design and archival research as a means of cultural analysis, we further expand conversations on design research methods within human-computer inter- action (HCI), using design to reveal legacies of practice Figure 1: Close up view of the Core Memory Quilt. elided by contemporary technology cultures.

    R-700 MIT’s ROLE IN PROJECT APOLLO FINAL REPORT ON CONTRACTS NAS 9-153 AND NAS 9-4065 VOLUME I PROJECT MANAGEMENT SYSTEMS DEVELOPMENT ABSTRACTS AND BIBLIOGRAPHY edited by James A. Hand OCTOBER 1971 CAMBRIDGE, MASSACHUSETTS, 02139 ACKNOWLEDGMENTS This report was prepared under DSR Project 55-23890, sponsored by the Manned Spacecraft Center of the National Aeronautics and Space Administration. The description of project management was prepared by James A. Hand and is based, in large part, upon discussions with Dr. C. Stark Draper, Ralph R. Ragan, David G. Hoag and Lewis E. Larson. Robert C. Millard and William A. Stameris also contributed to this volume. The publication of this document does not constitute approval by the National Aeronautics and Space Administration of the findings or conclusions contained herein. It is published for the exchange and stimulation of ideas. @ Copyright by the Massachusetts Institute of Technology Published by the Charles Stark Draper Laboratory of the Massachusetts Institute of Technology Printed in Cambridge, Massachusetts, U. S. A., 1972 ii The title of these volumes, “;LJI’I”s Role in Project Apollo”, provides but a mcdest hint of the enormous range of accomplishments by the staff of this Laboratory on behalf of the Apollo program. Rlanss rush into spaceflight during the 1060s demanded fertile imagination, bold pragmatism, and creative extensions of existing tecnnologies in a myriad of fields, The achievements in guidance and control for space navigation, however, are second to none for their critical importance in the success of this nation’s manned lunar-landing program, for while powerful space vehiclesand rockets provide the environment and thrust necessary for space flight, they are intrinsicaily incapable of controlling or guiding themselves on a mission as complicated and sophisticated as Apollo.

  • Microprocessor History Lession MICROPROCESSORS and MICROCONTROLLERS I
    Microprocessor History Lession MICROPROCESSORS AND MICROCONTROLLERS I 1 1947 Electronics: William Shockley, John Bardeen and Walter Brattain build the first practical point-contact transistor at Bell Labs 2 Apollo Guidance Computer (AGC) makes its debut 1960s Early Embedded System 3 Apollo Guidance Computer Designed by scientists and engineers at MIT’s Instrumentation Laboratory, the Apollo Guidance Computer (AGC) is the culmination of years of work to reduce the size of the Apollo spacecraft computer from the size of seven refrigerators side-by-side to a compact unit weighing only 70 lbs. and taking up a volume of less than 1 cubic foot. The AGC’s first flight was on Apollo 7. A year later, it steered Apollo 11 to the lunar surface. Astronauts communicated with the computer by punching two-digit codes into the display and keyboard unit (DSKY). The AGC was one of the earliest uses of integrated circuits, and used core memory, as well as read-only magnetic rope memory. The astronauts were responsible for entering more than 10,000 commands into the AGC for each trip between Earth and the Moon. 4 5 There is no consensus on who invented the IC. The American press of the 1960s named four people: Kilby, Lehovec, Noyce and Hoerni; in the 1970s the list was shortened to Kilby and Noyce. Kilby was awarded the 2000 Nobel Prize in Physics "for his part in the invention of the integrated circuit". In the 2000s, historians Leslie Berlin, Bo Lojek and Arjun Saxena reinstated the idea of multiple IC inventors and revised the contribution of Kilby.
