**82430LX     PCIset (Pentium) LX (Mercury) (82433LX/82434LX) 03/22/93
***Notes:
Date source: TimelineDateSort7_05.pdf

Originally known as the 82430 chipset

Information taken from:
          1.              82420_PCIset_ISA_and_EISA_Bridges_Mar93.pdf
          2.                     Intel_Peripheral_Components_1994.pdf
          3: 1995_Intel_Pentium_Processors_and_Related_Components.pdf*

>* Datasheet is for LX and NX variants. 

Each source has 3 datasheets:
                        1.               2.       3:
General 82430          Mar'93            Oct'93   Nov'94
82434LX (PCMC)         none*             Nov'93   Dec'94
82433LX (LBX)          none*             Oct'93   Dec'94
>* will use the date Mar'93

Differences Between Mar'93 and Oct'93/Nov'93:
General Section:
  References in the Mar'93 datasheet  to the 82378IB have been changed
  to  the  82378  in  the  Oct'93, Indicating  the  82378ZB  has  been
  introduced.

82434LX Section:
  Only a minor difference,"CPU/Cache" changed to. "CPU/Cache and  DRAM
  subsystem" at last part of first paragraph.

82433LX Section:
  Some features worded slightly differently, changes shown in the text

Differences Between Oct'93/Nov'93 and Nov'94/Dec'94:

  This datasheet includes  information relevant to both  the 430LX and
  430NX. The datasheet  is arranged such that all  text describes both
  chipsets, except shaded  areas of text, that describe  how the 430NX
  differs.  Any of these sections that only describe the 430NX are not
  quoted in  the Info and  features section. The same  datasheet, with
  these sections is quoted in the 430NX section.

General Section:
  Some features worded slightly  differently, none significant. Except
  for the later datasheet claiming both the 430LX and NX support 512MB
  ram. This is a misprint, or  clumsy wording.  The Info section makes
  specific  reference  to the  82378ZB  variant.   Also the  82375/374
  combination  is  referred  to  as  the  82375EB/SB  and  82374EB/SB,
  indicating the newer EB variant is now available.

82434LX Section: 
  A minor difference in the features section, see changes in the text.
  Aside from references to the  NX variant, the info section the same,
  except that it  ends just before the sentence  "Up to twelve single-
  sided SIMMs..."

82433LX Section:
  Some  features worded slightly  differently, Mainly  "host" replaced
  with "CPU", other  changes shown in the text.  Aside from references
  to the NX variant, the info section is the same.
