Let's take a trip down memory lane to 1968. Here are the Data Processing personnel in the City Administration Building basement. IBM 360 computer, teletype interface, and hard drives were in use. The IBM System 360 was a mainframe computer system announced by IBM in 1964 and delivered between 1965 and 1978. It was the first family of computers, which were designed to cover the complete range of applications, from small to large, both commercial and scientific. Nearly 60 years later, the City of San Diego has their own Information Technology department that handles the innovative computer systems and applications to ensure that various departments are safe and secure for decades to come.
