If there is no reference number, it is because I cannot find the source of the information, but know that it is reasonably accurate. In some cases I could come no closer to the correct date than the year in which it happened. The dates given for the various entries found here are as accurate as I can make them, based on the sources cited in the footnotes that follow. The Apple II Timeline gives an overview of many of the events mentioned in the Apple II History, as well as some others that are not discussed.
