"Mac computers run the TNT products through the unique MicroImages X Server (MI/X), which MicroImages supplies with every TNT product for Macintosh.
MicroImages is also pleased to make this X Server freely available for Macintosh users who do not have any of the TNT products. You may want to use your Power Macs as X terminals in a network environment -- MI/X works fine as an X terminal emulator. You may also want to make your PC a true X Server and run multiple X clients from your desktop. MI/X works fine there, too -- after all, that's why MicroImages developed MI/X in the first place.
