NCOS is the graphical user interface-based operating system developed for use in Oracle Corporation's Network Computers, which are discontinued.[1] It was adapted by Acorn Computers from its own RISC OS,[2][3] which was originally developed for their range of Archimedes desktop computers. It shares with RISC OS the same 4 MB ROM size and suitability for use with TV displays.

In 1999, Pace acquired the set-top box (STB) division of Acorn Computers,[4]: 5: 9 this being a component in the disposal of assets around the takeover of Acorn by MSDW Investment Holdings.[5] This gave Pace the rights to use and develop NCOS.[6] RISCOS Ltd later announced Embedded RISC OS, which was to have similarities with NCOS.[7]
