 ### Copyright
 
-The original copyright on the document is clearly still held by Intel. It was published by someone in 1976, so presumably the copyright won't expire for at least another 20 or so years. However, I'm just hoping that nobody cares enough about a document that is almost useless today, besides the small niche of people still playing with 8080-based systems.

+### License
+
+Because of the ambiguous legal situation, I've decided to put *my work* under CC BY-NC-ND -- attribution, non-commercial, no derivatives. I rarely use this combination, but because I definitely cannot give permission to create derivative works, I figured this was the best middle ground. You can basically print this out and share it with people, but you can't use it commercially (which would probably annoy Intel) and you can't create derivative works. See [LICENSE.txt] for details.
