ISR installed an IBM 360/40 mainframe computer, dramatically improving the institute’s computing capabilities. Soon after, the Computer Services Facility designed a new system of general and special-purpose software, OSIRIS, to run on the 360/40. The software, used for data management, statistical analysis, and display, was quickly adopted by ISR researchers, and later versions became a mainstay of the international research community. OSIRIS remained the standard software for ISR until 1991.
