is the Mac OS X based run-time component from IMG's Build-A-Board. It is made available as a separate purchasable product for certain customers that prefer the license per unit, rather than the platform licensing available within Build-A-Board.

The actual code-base for the run-time targets is a combination of target specific code, shared core keyboard software code, and shared lower-level abstracted operating system API code. Because the foundation was designed to be cross-platform, and extensible, the ability to run the same keyboard layout (Data) on multiple run-time targets (Programs) is the expected operation.
