Unfortunately, Google doesn't yet have a tool for searching by chronology. Many of their links are "dead" and many more are aged beyond reason. Often their results point to magazine pages that no longer contain what they "should" and many other times, they no longer should be read by persons wishing reasonable information.

Magazine articles and even manufacturer-published app-notes are notoriously error-laden. I don't know why people don't review this sort of material, but, seemingly, they don't.

The original articles, dating back to 2000/2001 regarding the DS89C420 still provide the misleading information that the MCU is capable of 50 MIPS. That's been withdrawn.

One thing I find annoying about DALLAS Semi's datasheets is that they often omit a list of signal definitions, BTW, as do many websites. It's often important to know whether a given signal is active-high or active, low, particularly with clones of Intel products, since Intel seemed to like positive-going interrupts, resets, etc. While details such as the active state of a signal are readily deduced from timing details, it makes sense to me that they should be included in a list of precise signal definitions, which are often lacking in 805x-series datasheets, probably because assumptions about their application have been made.
