**82420TX/ZX PCIset (for 486) TX (Saturn), ZX (Saturn II) c:Nov92

>* General 82420 datasheet, 82423 and 82424 all dated Oct'93.
>** see archived sources at the end of this section
Differences:
Nov'92 to Mar'93:
The Mar'93 datasheet (Both only include the general section) has a
completely restructured Info and Features section. The main func-
tional difference is that in the Nov'92, no PCI-EISA bridge version
is available. The Mar'93 is the earliest datasheet found that
mentions the 82374/82375 EISA components.
Mar'93 to Oct'93:
The Mar'93 datasheet refers to the 82424TX component directly, the
Oct'93 to just 82424. Same with 82423TX and 82423. This is due to
the datasheet specifying both the TX and ZX variants of both chips.
A similar thing occurs with the 82378IB and 82378. In Oct'93 there
were IB and ZB variants. Other differences are shown in the text.
The Mar'93 source only includes the general section. In Oct'93, both
datasheets found for the specific chips are only short 1-2 pages
long.
In Errata:1, more specifics are given, that partially contradict the
Oct'93 datasheet. Dated Aug'93 the following differences are given:
"
82424TX * Name change from 82424TX to 82424ZX
Changes: * ZX eliminates all known TX errata
* Features/Enhancements include: Extra RAS line supports
additional memory, Optional memory locations for SMM,
external work-around logic for TX eliminated
Timing:
We anticipate production shipments...in October 1993 for the
82424ZX. "
Errata:2 gives further details. The document itself is undated, but
Errata:1 is hyperlinked to it. Its text is quoted in the Versions
section. Errata:3 & 4 go into further detail.
All Errata documents contradict the Oct'93 datasheet, by making no
mention of the 82423ZX variant.
Oct'93 to Nov'94:
In the Nov'94 datasheet specific variants are now referred to again.
All references to 82424 are replaced with 82424ZX, 82378 replaced
with 82378ZB. The 82423 is replaced with 82423TX again. It appears
the 82423ZX variant either no longer exists, or the Oct'93 datasheet
refers to a chip that was planned, but never introduced. As the
Oct'93 datasheet for the 82423 specific chip is only a part data-
sheet (1-2 pages), it has been impossible to determine what the
differences are between the ZX and TX variants, or even if the ZX
variant actually existed. It simply states there are differences.
The specific datasheet for the 82424 now only refers to the ZX
variant. the ZX-50 variant is not mentioned. Other changes between
the datasheets are shown in the text.
Errata:5 contains links to additional information, some related to
this chipset.
