I haven't looked at them yet. But hopefully the first 256 bytes will give insight on how to get to the rest.
The slot ROM (256 bytes) clearly reads the disk to determine whether it is a 13-sector format or a 16-sector format, but the $C800 space deosn't appear to belong to the disk controller. It can be a little tricky to save, since it must be mapped in, moved to a safe space, and then saved. Otherwise, any other extended ROM activity will disable the disk controller's $C800 ROM. -michael NadaNet networking for Apple II computers!
