September 7th 1982 LISA Hardware Manual LISA HARDWARE MANUAL Forrest Warthman and Associates Final Draft September 7th 1982 Author: D. Berry September 7th 1982 LISA Hardware Manual PREFACE (Full Version Only) The LISA Hardware Manual is concerned with the internal functioning of the LISA system. It is intended for use by people concerned with the detailed functional operation of the LISA hardware. It is divided into two sections. Section I provides information on the functional performance and specification of the system. Chapter 1 provides a general introduction to the Lisa system, while giving a brief description of the system architecture. Chapter 2 will be of interest to programmers who need to know the address and interrupt structure, as well as the operation of the Memory Mapping Unit. Chapter 3 contains in!ormation on dimensions and environmental requirements and interfaces to the system, which are of use to design engineers wishing to interface to the Lisa. Section II of the· manual contains full functional. descriptions and theory of operation for each of the modules in the Lisa system. It will not be of interest to the general reader and is intended for use only by design and service personnel. Section II includes chapters on: * * * * * * * * The _processor board The memory board The I/O board The video board The operator interface The floppy disk unit The power supply System assembly The appendices supply schematics for the system components. Other documents relevant to the system are: * * * * LISA Hardware Manual (Condensed Version) LISA Floppy Disk Drive Manual LISA Owner's Guide LISA Operating System Manual * * * * * * Motorola 68000 User's Manual Motorola 6504 User's Manual Motorola 6522 Data Sheet COPS42l User's Manual 8530 sec User's Manual AMD 9512 Data Sheet xii LISA Hardware Manual September 7th 1982 TABLE OF CONTENTS Preface -- Section I -- Chapter 1 1.1 1.2 1.3 1.4 1.S 1.6 1.7 1.8 Chapter 2 SYSTEM ARCHITECTURE System Layout • • • • • • • • • • 1-1 Hardware Structure • • • • • • • • • • 1-4 The Central Processing Unit • • • • • • 1-6 f-temory • • '. • • • • • • • • • 1-6 Internal Buses • • • • • • •• •• 1-10 Storage Media • • • • • • • • • • • • • 1~11 User In'terfaces • • • • • • • • • • • • .1-11 Additional Features • • • • • • • • 1-11 SYSTEt-t PROGRAUMING 2.3 ..·.·.. 2-1 CPU Registers and Their Osp. · . . • .•.• 2-2 Memory Management Scheme 2-3 · · ·· •• ·· ·· •· 2-5 2.3.1 Address Transformation 2.3.2 The MMU Registers • 2-8 · · · · · · 2.3.3 MMU Initialization 2-11 2.3.4 System Contexts • · · · · · · · • ·• ·• 2-13 2.4 Addressing in Special I/O Space • • • • 2-15 2.5 System I/O Map.
