Modern, cross platform library of functions used in CoCo software
This is a modern set of libraries intended for use in software related to the Tandy Radio Shack Color Computer (the CoCo). Some functionality may also be useful in more general Motorola 6809 centered projects.
CocoCommons provides a set of libraries for common tasks such as reading DECB and RBF filesystems, interpretting common file formats, and displaying CoCo-like screens. These are used extensively in the DriveWire 4 project and the upcoming nineserver project.
