 # ProDOS-Utilities
 This project is just starting but is intended to be both a command line tool and library to provide access to ProDOS based hard drive images. It is written in Go to be cross platform (Linux, Windows, macOS etc.). Functionality, naming and parameters are subject to change without notice. This project was started so I would be able to automate writing the firmware file into the drive image for one of my other projects [Apple2-IO-RPi](https://github.com/tjboldt/Apple2-IO-RPi).
