TempleOS (formerly: J Operating System, SparrowOS and LoseThos) – a lightweight operating system designed to be a Temple to Jesus Christ, developed by Terry A. Davis. Terry A. Davis has spent 12 years attempting to create the operating from scratch. Terry explains that God has instructed him to construct a temple.
TempleOS is an x86_64, multi-tasking, multi-cored, public domain, open source, ring-0-only, single-address-map (identity-mapped), non-networked, PC operating system for recreational programming.
The TempleOS is written in HolyC (a variation of C) and uses an interface similar to a mixture of DOS and Turbo C.
It has keyboard and mouse support, and ISO 9660, FAT32 and RedSea file systems (created by Davis) with support for file compression. It runs 8-bit ASCII with graphics in source code and has a 2D and 3D graphics library, which run at 640×480 VGA with 16 colors. The operating system includes an original flight simulator, compiler, and kernel.
