Can anyone point me to some documentation on how to do this? Also, any update on when the EDD+ clone card will be available? I have an original EDD+ card. Can I use this with Saltine's Super Transcopy (SST)? As you can tell, I'm clueless on this topic. ;) Thanks RickStep by step here: http://apple2.org.za/gswv/a2zine/Docs/SaltinesSuperTranscopyDocs.txt SST uses standard floppy controllers, not EDD+. Basically it creates 2 DSK images from the original disk. Then in an emulator SST combines the 2 DSKs into a NIB. (Or you can do that combining step with Ciderpress.)
You should also be aware that many protection schemes cannot be represented in a .nib file. I've never seen a study of what fraction of protected disks *can* be handled by .nib imaging, but I'm sure that it decreases with time, since later copy protection schemes were much more complex and could not be represented as 35 (or 36) tracks. For these more highly protected disks, the only known way to run them on an emulator is to de-protect (or "normalize") the disk, then image it as a standard .dsk image. The only method for normalizing a disk is to do a lot of human detective work (which for many was much more challenging than playing the game ;-). If the program writes to the disk as well as reading from it, then extensive changes may be necessary to adapt it to a normal format. -michael ******** Note new website URL ******** NadaNet and AppleCrate II for Apple II parallel computing!
