**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.
