Does anyone have a good primer on the Disk II data encoding scheme, Group Code Recording (GCR)?
I'm looking to archive my various Apple II floppies. I know PC disk controllers can't read them, but I have a Catweasel "universal" floppy controller. I hope to modify some of the software that comes with the card to read the Apple diskettes and need to understand the technical details around the actual physical disk format.
