-
- Magic. Any technology that's sufficiently advanced...
- or in layman's term: stuff manufacturers won't tell you.
-
- Because there are differences between how the two are implemented.
- Simply put if you program a 16V8A as a 16V8, it won't do what you
- intented to do. Beyond that I am not supposed to say more.

-
- The Jedec fuse map for the different parts are available in Data books.
- In fact the Elektor article (April issue) is almost enough to get you
- start programming 16V8 & 20V8 (not the A parts however). Every single
- sentence there is vital info. Be sure to read it 4 or 5 times.
