CFM-68K is a new runtime architecture for 68K-based Macintosh applications and shared libraries. The new architecture is modeled after the Power Macintosh runtime architecture and uses CFM-68K (the Code Fragment Manager for 68K Macintosh) to provide shared library support. CFM-68K runtime applications and shared libraries can coexist and run simultaneously with classic 68K runtime applications.
CFM-68K Runtime Software Installation
The CFM-68K runtime software requires System 7.1 or later, 32-bit addressing to be turned on, and a 68020, 68030, or 68040 Macintosh system.
To install the CFM-68K runtime software and related shared libraries, drag the file called CFM-68K Runtime Enabler, as well as all the shared library files in the folder, from the “:CFM-68K Additions:” folder to the System folder icon (not into an open System folder) on your 68K-based Macintosh system. This copies the files into the Extensions folder. After installation, reboot your system.
Documentation on how to develop software that takes advantage of CFM-68K is in the "Bldg CFM-68K Runtime Programs" folder.
