Digital Radio Technology and Applications
it DIGITAL RADIO TECHNOLOGY AND APPLICATIONS Proceedings of an International Workshop organized by the International Development Research Centre, Volunteers in Technical Assistance, and United Nations University, held in Nairobi, Kenya, 24-26 August 1992 Edited by Harun Baiya (VITA, Kenya) David Balson (IDRC, Canada) Gary Garriott (VITA, USA) 1 1 X 1594 F SN % , IleCl- -.01 INTERNATIONAL DEVELOPMENT RESEARCH CENTRE Ottawa Cairo Dakar Johannesburg Montevideo Nairobi New Delhi 0 Singapore 141 V /IL s 0 /'A- 0 . Preface The International Workshop on Digital Radio Technology and Applications was a milestone event. For the first time, it brought together many of those using low-cost radio systems for development and humanitarian-based computer communications in Africa and Asia, in both terrestrial and satellite environments. Ten years ago the prospect of seeing all these people in one place to share their experiences was only a far-off dream. At that time no one really had a clue whether there would be interest, funding and expertise available to exploit these technologies for relief and development applications. VITA and IDRC are pleased to have been involved in various capacities in these efforts right from the beginning. As mentioned in VITA's welcome at the Workshop, we can all be proud to have participated in a pioneering effort to bring the benefits of modern information and communications technology to those that most need and deserve it. But now the Workshop is history. We hope that the next ten years will take these technologies beyond the realm of experimentation and demonstration into the mainstream of development strategies and programs. -
Ngos) RELATED to UNEP PROGRAMMES
ENVIRONMENTAL ACTIVITIES OF NON-GOVERNMENT ORGANIZATIONS (NGOs) RELATED TO UNEP PROGRAMMES REPORT AND DIRECTORY PREPARED FOR THE EIGHTH GOVERNING COUNCIL OF THE UNITED NATIONS ENVIRONMENT PROGRAMME April 1980 ENVIRONMENT LIAiSON CENTRE NAIROBI. KENYA foreword For the third time the United Nations Environment Programme has oo-operated with the Environment Liaison eentre (ELC) in the survey of NGO activities in subject areas to be reviewed in-depth by the Governing Council of UNEP at its eighth session (April 1980) and in the production of this report on the findings of the survey. We believe that the information contained in the Report will be valuable to Governments during and after the Governing Council and to others interested in the work of the NGO community to which UNEF attaches great importance. The success of a survey of this kind would not have been possible without the final cooperation of the NGOs with the ELC. Such cooperation constitutes a con- crete example of their commitment to the cause. I therefore wish to express our appreciation to the many NGOs that responded to the enquiries of the ELC during 1979 and earlier, and thus made possible the compilation of this report which provides supplementary information to that in the report of the Executive Director on the environment programme during the eighth session of the UNEP Governing Council. Although collected with the Support of UNEP, the views expressed in this report are not necessarily those of UNEP. Mostafa K. Tolba Executive Director United Nations Environment Programme -

Oral History Panel on the Development and Promotion of the Intel 8008 Microprocessor Participants: Federico Faggin Hal Feeney Ed Gelbach Ted Hoff Stan Mazor Hank Smith Moderated by: Dave House Recorded: September 21, 2006 Mountain View, California CHM Reference number: X3706.2007 © 2006 Computer History Museum Oral History Panel on Intel 8008 Microprocessor Dave House: Stan, tell us how the 8008 began. Stan Mazor: Well, in today’s personal computers, we have RAM and we have flat panel displays, but in the middle of the ‘60s, we had core memories on our minicomputers and we typically used either a teletype or a CRT terminal (cathode ray tube). We also nicknamed these “glass teletypes” because they played the role of the teletype, but they were much faster. The key ingredient to the CRT terminal in those days was the shift register; there was no RAM memory in those days. Shift register were being provided by General Microelectronics, (GME), General Instrument and some other companies. When Intel got started in 1969 in the memory business, we were designing RAM components-- and we really had no customers for them. So one of the things that we did was---to do a custom order for Datapoint (formerly Computer Terminals Corporation) who was one of the makers of a cathode ray terminal, and we made for them a 512-bit re-circulating shift register. So this gave us a ready customer and it was a type of memory product which was in use at that time. Well, Datapoint, having been in the display [terminal] business, had an idea of going into the business terminal [computer] business; in addition and they had a clever idea, which was to use the shift registers that they were already using inside the display terminal as the main memory of their computer. -

Oral History of Victor (Vic) Poor
Oral History of Victor (Vic) Poor Interviewed by: Gardner Hendrie Len Shustek Recorded: December 8, 2004 Melbourne, Florida CHM Reference number: X3110.2005 © 2005 Computer History Museum Oral History of Victor (Vic) Poor Gardner Hendrie: Vic Poor has agreed to an oral history interview for the Computer History Museum and, right at the beginning, we thank you for being willing to do this. I think probably maybe the best place to start. Could you tell us a little bit about your family background, siblings, where you grew up, you know, when you were born, some of those things. Victor Poor: Why? Does that have anything to do with computers? <laughs> Hendrie: Huh? Poor: I said, does that have anything to do with computers? Hendrie: Well, what it actually does is, there's a clear association with people's early background and what they ended up doing. Poor: Well, I'm a native of California, born in Los Angeles and I have-- I had one sister, who is also still alive, now lives in Seattle. But I was actually raised in San Diego, which was where I lived until I finished high school. My parents tell me that I was fascinated by radio and that, as soon as I was old enough to reach the knob on our Philco shortwave set, I was mesmerized by the radio. I certainly can't remember that but I do remember becoming a ham radio operator early on in life and I've always been a active ham radio operator. Hendrie: What were your parents occupations? What did they do? Poor: My mother was a public health nurse and my father was a construction.. -
