**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.

'The 655xx series chips are SVGA video controller chips for flat panel
displays and CRTs. They also provide  some level of CGA, MDA, EGA, and
Hercules  compatibility, and  various accelerator  features. They  are
designed  with various  features  for reducing  power consumption  and
optimizing display quality.
