The Apple Sophisticated Operating System 1.3 (Apple SOS 1.3) is a primary operating system developed by Apple in 1982, especially for the Apple III Plus computer. SOS 1.3 has been publicly released on November 1, 1982, and was an updated version of the original Apple SOS.
Apple Sophisticated Operating System is a single-tasking single-user operating system. It makes the resources of the Apple III available in the form of a menu-driven utility program as well as a programming application programming interface (API). A single program is loaded at boot time, called the interpreter. Once loaded, the interpreter can then use the SOS API to make requests for the system.
Today Apple Sophisticated Operating System 1.3 is 39 years old!
