Once you have everything, install Stuffit Expander, unstuff the disk image to a new folder on your hard disk, and name the folder something short, like "Mac." Copy the RAWRITE program into this same folder. Rename the image file to image.img.

The problem I am having is that Stuff it expander does not unstuff the archive as a disk image but as a .sea file. This is where I think that I'm either making a mistake, or the current version of Stuffit expander for windows handles .sit.bin differently then earlier versions.
