**Who made the first chip set?
By the criteria of (2.) in 'Definition of a chip set' many sources
state this to be the Chips and Technologies NEAT chip set. I don't
know why this is stated as it is most definitely incorrect. The CS8221
NEW Enhanced AT (NEAT) chip set consisting of the chips;
82C211/82C212/82C215/82C206 was as far as I can establish, first
released sometime in 1986.
C&T itself have an earlier chip set called the CS8220 PC/AT compatible
Chip Set, and consists of the following chips; 82C201/82C202/
82A203/82A204/82A205. It was first available in OCT-85. (see:C&T>
CS8220>Notes for further info.)
That is, AFAIK, the first motherboard chip set from C&T and AFAIK the
worlds first chip set that meets the criteria of (2.). However C&T did
already have on the market their popular EGA chip set, but that isn't
a motherboard chip set.
By the criteria of (1.), IBM, or Intel, see IBM>PC/XT chip set.
Another pre-'86 chipset is the Faraday FE2010. The datasheet includes
a schematic on the very last page dated 11/22/85. This only indicates
the chip set was on paper at that date. An acutal release date has not
been found.

"In 1990 the company introduced Single Chip AT Controller (SCAT)
technology, by which the functionality previously found in chipsets
could be integrated into one chip. In turn, integrating several SCAT
chips, the company introduced the Entry-Level Enhanced AT (ELEAT)
CHIPSet, a platform incorporating systems logic, graphics, data
communications, mass storage, and BIOS."
