This says that Terry didn't release the source code for the kernel or the bootloader. I'm not sure if I'm reading that correctly, since the entirety of TempleOS was built within TempleOS:

- Kernel: https://github.com/cia-foundation/TempleOS/tree/archive/Kern...

- Bootloader: https://github.com/cia-foundation/TempleOS/tree/archive/Adam...

- Bootloader documentation: https://github.com/cia-foundation/TempleOS/blob/archive/Doc/...
