An Interview With
An Interview with WARREN PRINCE OH 413 Conducted by Jeffrey R. Yost on 4 April 2012 Computer Services Project Sunnyvale, California Charles Babbage Institute Center for the History of Information Technology University of Minnesota, Minneapolis Copyright, Charles Babbage Institute Warren Prince Interview 4 April 2012 Oral History 413 Abstract Warren Prince was an executive at Tymshare and served as the leader of TYMNET. He served on the management team at McDonnell Douglas after it acquired TYMNET. The interview concentrates on TYMNET’s history and explaining and providing context to some of the documents he provided for the interview. 2 Prince: So will you produce the chapter in your book out of audio? I’ve got a bunch of papers that might be of interest or might not. Yost: Terrific, I would. Prince: Because it kind of shows; first, on the TYMNET side it shows the growth of it and really, the initial problems of it, which graphically shows it instead of saying it. And then the McDonnell Douglas part. Anyway, we can get into that when the time comes. Yost: Sounds good. My name is Jeffrey Yost, from the Charles Babbage Institute at the University of Minnesota, and I’m here today on April 4th, 2012, with Warren Prince of Tymshare and TYMNET. I’d like to begin just with some brief biographical stuff. Could you tell me where you were born, where you grew up? Prince: Born in Walnut Creek, California but grew up mostly in Arizona; Glendale, Arizona. And went through; started at the University of Arizona, and then joined the Army. -

This book provides in depth knowl- edge on telecommunication switching and good background for advanced studies in communi- cation networks. The entire subject is dealt with conceptual treatment and the analytical or mathematical approach is made only to some extent. For best understanding, more diagrams (202) and tables (35) are introduced wherever necessary in each chapter. The telecommunication switching is the fast growing field and enormous research and development are undertaken by various organizations and firms. The communication networks have unlimited research potentials. Both telecommunication switching and communication networks develop new techniques and technologies everyday. This book provides complete fun- damentals of all the topics it has focused. However, a candidate pursuing postgraduate course, doing research in these areas and the employees of telecom organizations should be in constant touch with latest technologies. -

This began with point-to-point communication between mainframe computers and terminals, expanded to point-to-point connections between computers and then early research into packet switching. Packet switched networks such as ARPANET, Mark I at NPL in the UK, CYCLADES, Merit Network, Tymnet, and Telenet, were developed in the late 1960s and early 1970s using a variety of protocols. The ARPANET in particular led to the development of protocols for internetworking, where multiple separate networks could be joined together into a network of networks. In 1982 the Internet Protocol Suite (TCP/IP) was standardized and the concept of a world-wide network of fully interconnected TCP/IP networks called the Internet was introduced. -
