AS: The first computers I built were data-acquisition systems. Their job was to monitor defects. They were a wire-programmed system, which means that they were uniquely designed to do just that job. Another computer called GE-312 monitored a turbine for Southern California Edison. We didn’t dare to control it because that required stops and starts, which could have endangered the machine’s life. The function then was just to make sure that it stayed within specified temperature ranges and that all the contacts were opened or closed as prescribed.
