The GNU MIX Development Kit (GNU MDK) is a free software package for developing, running and debugging programs written in MIXAL, an assembly-like language for programming a hypothetical computer called MIX. GNU MDK is part of the GNU Project.

Current versions of MDK for different platforms are free to download from the project web site.
