Mac Ivory User S Guide

MacIvory User’s Guide Preface MacIvory provides the benefits of symbolic processing along with the features of a Macintosh personal computer. Before using your MacIvory, read "Introduction to MacIvory Machines" (this will familiarize you with the system). Then, read the user documentation supplied by Apple, and the disk drive and monitor manufactur- ers, so that you will feel confident about using the Macintosh computer, and the MacIvory system’s components. Once you are familiar with your MacIvory, its components, and the Macintosh user interface, return to this manual. Begin by reading and following the steps in "Get- ting Started with MacIvory" to position and power up your MacIvory System. This book is divided into two main sections: a user’s manual and a programmer’s reference. The user’s manual can help you to get started using MacIvory, and pro- vides information on some common Macivory operations. The programmer’s refer- ence provides information on how to use features of the Macintosh operating sys- tem from Genera and other topics for programmers who are developing MacIvory applications. You may also want to refer to this additional documentation: • For information about adapting programs written on Symbolics 3600-series ma- chines to MacIvory, see the section "Porting Genera Applications to Ivory Ma- chines". • For information about the Genera 8.0 software and how it differs from Genera 7.4 Ivory, see Genera 8.0 Release Notes. For information about Symbolics ma- chines and the Genera software development environment, refer to the books contained within the Genera documentation set. New Symbolics users should refer to these titles first: ° Genera Workbook ° Site Operations ° Genera User’s Guide Overview of MacIvory The MacIvory system makes Symbolics’ Genera software environment, which en- ables the comprehensive development, prototyping, and delivery of applications, available to Apple Macintosh II users. Whenever possible, MacIvory maintains the Macintosh user interface paradigm for video, I/O processing and communications. The MacIvory board set plugs directly into the Macintosh II with no other system modifications required. Genera applica- tions can be "opened" under MacOS just like any other Macintosh window. Page 892 MacIvory software basically consists of two parts: Code that runs on the Ivory pro- cessor and code that runs on the Macintosh. The two processors communicate with each other through a special region of memory that they both access. MacIvory has exclusive use of a memory region allocated to it by the Macintosh when the Macintosh is powered on or restarted, and the Macintosh uses the rest of memory. All input/output is handled through the Macintosh. On the Ivory side, the code provided (written in Lisp) consists of: • A Remote Procedure Call (RPC) interface. • Genera modified as neces…
