PREFACE

About This Developer Note

This developer note describes the Macintosh PowerBook 2400c computer, a
new computer based on the same architecture as the PowerBook 3400
computer but smaller and lighter. This developer note describes only the
changes that make the new models different from the PowerBook 3400. For
information about the PowerBook 3400, see “Supplemental Reference
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
here. If you are not already familiar with Macintosh computers or if you
would simply like additional technical information, you may wish to read the
supplementary reference documents described in this preface.

Contents of This Note 0

This note has only one chapter: a delta guide describing the differences
between the Macintosh PowerBook 2400c computer and the PowerBook 3400
computer. Because the note is so short, it has no glossary or index.

Supplemental Reference Documents 0

have the developer note for that computer. Adobe Acrobat PDF (portable
document file) versions of all developer notes are available on the Developer
CD and on the Internet at

For a description of the versions of the Mac OS that come with the new

models, developers should refer to Technote 1090, “Mac OS 7.6,” and
