Abstract

Often in our hurry to create the future in computer engineering, we ignore lessons from past projects. One project that offers interesting insights, the IBM System/360 Model 91, has celebrated the 30th anniversary of its first shipment. The largest member of the series based on IBM´s most enduring and influential computer architecture, this machine owed much to its predecessors. Together, these machines show us what the state of the art in computer processors was like in the 1960s, when IBM announced the S/360 and illustrate how far computer engineering has come in 30 years. The author considers how the Model 91´s story shows just how far computer architecture has come since 1967. It may also reveal how practitioners must change to ensure continued innovation in computer engineering
