CHRONICLES AS A REGENERATIVE RECORDING, SYSTEM TESTING, AND ANALYSIS CONCEPT FOR SAGE AND OTHER REAL-TIME DIGITAL SYSTEMS
Abstract
Chronicles is introduced as an experimental recording vehicle which can regenerate an original computer test run in its entirety by playing back all the recorded inputs into the operational program. Although the playback no tion is ancient history, the successful practical application of total system playback is recent and new for complex systems such as SAGE. Chronicles recording in SAGE emerged from an experimental DCA Model 8 design to its present experimental status in Model 9. Current applica tions of Chronicles in five SAGE studies are reviewed, demonstrating its versatility and some of the problems encountered in controlled system tests and exploratory investigations. A comparison with other SAGE recording vehicles indicates that Chronicles increases the useful ness of conventional recording and makes possible entirely new types of recording. Some possibilities for its extended use in SAGE are suggested for military, training, and program ming applications.
