This developer note is a supplement to the Macintosh PowerBook Duo Developer Note, described in the section “Supplementary Documents,” later in this preface. This developer note is intended to help hardware and software developers design products that are compatible with the Macintosh products described in the note. If you are not already familiar with Macintosh computers or if you would simply like more technical information, you may wish to read the supplementary reference documents described in this preface. Contents of This Note 0 This developer note is arranged in seven chapters and an appendix: ■ Chapter 1, “Introduction,” describes the Macintosh PowerBook Duo 2300c computer and compares it with other PowerBook Duo models. ■ Chapter 2, “Architecture,” describes the architecture of the computer, with emphasis on the PowerPC 603 microprocessor and the custom ICs. ■ Chapter 3, “Input and Output Features,” describes the input and output features and the internal hard disk drive.
