ZachOS – a small, open-source, MikeOS based 16 Bit X86 operating system. The goal is to create an OS that was very small in size but fun to use at the same time.

The developer wanted to remove all the complex layers of abstraction that are present in the Operating Systems of today such as Graphical Interfaces and Networking etc etc and just have a simple OS that loads programs.
