_(NewOs | http://newos.sourceforge.net/) is an open source *(OS) with an emphasis on design and portability. It is largely implemented in C/C++, with a small amount of assembly. Full source is available

Currently, the system is mostly a kernel with a minimal amount of user space libraries and applications. Thus far, most of the work has been put into the kernel and other underlying support. As a result the system isn't that interesting from an end-user point of view (no gui, simple commands on a command line), but that can change given a moderate amount of work by the maintainers or any volunteers.
