It’s not Linux, it’s something entirely unique.

TempleOS is a 64-bit, non-preemptive multi-tasking,[8] multi-cored, public domain, open source, ring-0-only, single address space, non-networked, PC operating system for recreational programming.[9] The OS 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.[5] Like most modern operating systems, it has keyboard and mouse support. It supports ISO 9660, FAT32 and RedSea file systems (the latter created by Davis) with support for file compression.[10] According to Davis, many of these specifications—such as the 640x480 resolution, 16-color display and single audio voice—were instructed to him by God. He explained that the limited resolution was to make it easier for children to draw illustrations for God.[1]

When he was alive, he would be frequently banned from forums for getting into crazy arguments about esoteric code things. Also the racial slurs. A complicated but beautiful human being.
