_____________________________________________________________________________

This Note formerly documented the internal structure of the UniDisk 3.5, 
primarily for those interested in providing copy protection.  Apple Computer 
no longer supports copy protection schemes, and we strongly urge developers to 
make use of alternate methods to limit unauthorized duplication.

The internals of the UniDisk 3.5 are now documented in the Apple IIGS Firmware 
Reference.
