Apple SOS
The Sophisticated Operating System, or SOS ( /ˈsɔːs/), is the primary operating system developed for the Apple III computer. The system was developed by Apple Computer, Inc. and released in 1980. SOS makes the resources of the Apple III available in the form of a menu-driven utility program as well as a programming API.
The Apple III System Utilities program shipped with each Apple III computer. It provided what today would be called the end user "experience" of the operating system if the user were running it instead of an application program. The System Utilities program was menu-driven and performed tasks in three categories:
- Device-handling commands: Copy, rename, format, verify volumes (drives); list devices; set time and date
- File-handling commands: List, copy, delete, rename files; create subdirectories; set file write protection; set prefix (current working directory)
- System Configuration Program (SCP): Configure device drivers.

Famous quotes containing the word apple:
“A man may build a complicated piece of mechanism, or pilot a steamboat, but not more than five out of ten know how the apple got into the dumpling.”
