**Quote style:
To avoid  thousands of quote marks  and colliding with quote  marks in
the  text, I  have used  a modified  quotation style.   Anything in  a
section  titled "Info:"  or "Features:"  is a  quote from  a datasheet
unless otherwised stated in that  section.  In these sections anything
inside  [] is  an  annotation and  not part  of  the datasheet  unless
otherwise stated in that section.

Under any other section, the text is my own unless indicated with "".

Also  this document  does not  contain the  entire datasheet  for each
chip, usually only the first few pages are included to give an outline
of it. Some datasheets are 100s of pages other are only 1.

**Why this document is not GPL or a wiki
The document is copyright,  it is NOT GPL'ed text. While  the GPL is a
fantastic  idea, I  have chosen  not to  make this  freely copied  and
modified. The reasons are as follows:

1. GPL text tends to be  copied...EVERYWHERE. For example, if you look
   up a subject  on wikipedia, then try to get  more information, or a
   different perspective on  say about.com.  There you  find the EXACT
   SAME  TEXT.  This  is what  mirrors  are for.   It's an  unintended
   consequence,  but  it  can  lead  to  misinformation  being  spread
   everywhere. A bigger problem.

2. There seems to be fewer  and fewer informative websites. It used to
   be that  if you  searched for  something you  would find  a website
   about a particular  subject. Now you tend to  find the encyclopedia
   and often nothing else (well quickly).

In addition the majority of this text is quotes.

The wiki  concept is a good  idea, but they have  problems. Because no
one "owns" the  work they seem to  go to two extremes.   Either no one
maintains them, or there are edit wars. Also anyone can edit them.
