This is a summary of known implementations of ML/I, organised by operating system. There is also a summary organised by hardware platform.

The summary contains links to individual pages describing the particular implementations. These contain all known information about the implementation, as well as links to any extant documentation, source code, ready-to-run binaries, etc. All relevant material for an implementation can be found from its individual page.

In the implementation pages, reference is made to the implementation method. A description of the meaning of this can be found on the How ML/I is implemented page. In addition, the ML/I version refers to the version of the core ML/I logic; a list of versions can be found on the version history page. The implementation version is a separate version identifier local to a particular implementation.

Other known implementations are as follows; for these, no further information is available at present.
