The chapter proposes a three step framework to assist in the study of technological change in historical terms, using one class of technology, computational devices and computers, to illustrate the approach. Step one explores the economic dynamics of computing to demonstrate the value of studying a specified technology to gain insights about other forms of technologies. Second step attempts an understanding of users and historians respond to the issue of change. Finally, a framework for studying the role of change in technology is presented. Many examples are drawn from different periods in the modern history of information processing.
