***Overview (History):
The original chipsets used  by IBM for the PC and XT  are based on the
Intel iAPX 88  system.  Some additional components are  taken from the
MCS-80/85 system.   The iAPX 88  system consists  of the 8088  CPU and
support chips.  It is a modification of the iAPX 86 system (8086 CPU),
with the iAPX 86 having a 16-bit  external bus, and the iAPX 88 having
an 8-bit  external bus. The iAPX  86 system was formerly  known as the
MCS-86 system.

The chips used in  Both the PC/XT and the AT  were introduced by Intel
at various  different times over  approximately a decade  between 1975
and  1984.  In  addition there  are various  different revisions  of a
particular chip. Due to these differences, relying on a datasheet from
a particular  year alone, is  insufficient. So for a  particular chip,
differences between the datasheets are  noted. This information can be
found in the ****Notes section of  each chip. The information from the
datasheets, quoted  in this document,  is not the  complete datasheet.
The  actual datasheet  contains more  information.  This  is done  for
brevity.

Also included  is information about  forerunners of chips used  by the
IBM systems.  For example, the 8255 (forerunner to the 8255A) has been
included.   At  a bit  more  of a  stretch,  the  8257 (essentially  a
forerunner to the 8237) has also been included.
