TempleOS (formerly J Operating System, SparrowOS and LoseThos) is a biblical themed lightweight operating system created over the span of a decade by the American programmer Terry A. Davis. The software is a x86-64 bit, multi-tasking, multi-cored, public domain, open source, ring-0-only, single address space, non-networked, PC operating system for recreational programming. The operating system was designed to be the Third Temple according to Davis and uses an interface similar to a mixture of DOS and Turbo C. Davis describes the operating system as a modern x86-64 Commodore 64 with C in place of BASIC.

History
Development for TempleOS began in 2003 after Davis suffered from a series of manic episodes that left him briefly hospitalized for mental health issues.
Davis is a former atheist who believes that he can "talk with God" and that God told him the operating system he built was God's official temple. According to Davis TempleOS is of 'Divine' intellect due to the inspired nature of the code. According to Davis, God said to create the operating system with 640x480, 16 colors display and a single audio voice. The operating system was coded in a programming language developed by Davis in C/C++ called "HolyC". The OS runs a file system called "Red Sea".
Features
TempleOS deliberately has no network support. It runs 8-bit ASCII with graphics in source code and has a 2D and 3D graphics library, which run at 640x480 VGA with 16 colors.
The OS contains numerous embedded biblical references including a program called AfterEgypt which allows users to "communicate with God" through an oracle.
