We want Technical Notes to be distributed as widely as possible, so
they are sent to all Partners and Associates at no charge; they are also
posted on AppleLink in the Developer Services bulletin board and other
electronic sources, including the Apple FTP site (IP 130.43.2.3). You can
also order them through Resource Central. As a Resource Central customer,
you have access to the tools and documentation necessary to develop Apple
II-compatible products. For more information about Resource Central,

We place no restrictions on copying Technical Notes, with the exception
that you cannot resell them, so read, enjoy, and share. We hope Apple II
Technical Notes will provide you with lots of valuable information while
you are developing Apple II hardware and software. The following pages
list all Apple II Technical Notes that have been released.
This Technical Note batch was originally released in May 1992. Since
that time, many of the contact addresses have changed and some
typographical errors have been fixed. To note these changes, this
document now bears the date June 1992. No content of any Notes has
changed since May 1992.
