The ASMIX Commands and Utilities project is an attempt to re-write as many of the usual Unix utilities in pure assembly language as possible. This turns them into unbelievably small static binaries which use only kernel system-calls (no libraries whatsoever). It supports the x86, PPC, PDP11, and SPARC platforms. This project has been abandoned since 2001.
Release Notes: The package was level-set on all supported platforms and systems, except unix/pdp11, for now. There are 6 working utilities on every system.
