# The OS-3o3 Operating System
## Project Summary
The goal is to have a 100% public domain 32-bit minmal operating system.
But we use open source third-party code to speed up the development.
We will replace them by pure public domain code when we will have enough resources.
Features include :
- i386 and "custom" architecture
- Graphic framebuffer (standard: 640x480 monochrome)
- Keyboard + Mouse or touch screen
- (USB or SDcard) Mass Storage (FAT32)
- Audio Device (mono 8kHz/8-bit in/out)
## License

### Quick start on Debian host :
```
sudo apt install lld llvm clang git qemu-system
git config http.postBuffer 524288000
git clone https://github.com/3-o-3/3o3.git
./configure.cmd
cd bin
make
```
