**Intro:
The information  contained within this  file should not  be considered
100%  correct.   Where  possible   information  has  been  taken  from
datasheets, however  even this info  may be incorrect.  The datasheets
state what  the chip should  do, not what  they actually do.  This is,
compounded further by different revisions of chips.

This  document will  never be  complete, and  I have  no intention  of
finding every  datasheet for  every chip  set. Some  of the  chip sets
listed are  from later systems  in the PIII/P4/Athlon era.   There are
many websites  with information on  these chip sets and  these entries
will likely not be expanded upon.  The focus of this document is early
PC/XT to  Pentium chip sets.  There are  few sites that  clearly illu-
strate this information, and how they relate to each other.

I  aim  to  prioritize   cataloging  significant,  rare  or  otherwise
interesting chip sets.

BTW the reason I wrote all of this down, is so that I could FORGET it.
Basically I needed to free  up some RAM.  I've  a head full  of arcane
snippets of  information on this subject.   I don't want to  end up  a
crazy old man  ranting random disjointed information  ("The C&T CS8220
came before the CS8221 you KNOW!") to disinterested passersby,  unable
to see how senile I've become. A side benefit, this might be useful to
someone else:-)
