Peripheral Interface Guide Introduction

Welcome to the eighth edition of the Apple $ ^{\circledR} $ Peripheral Interface Guide.

This guide contains interface information--pin-outs, switch settings, cabling requirements, and diagrams of interface ports--for Apple computers, interface cards, and peripherals. This information will help you connect Apple and non-Apple peripherals to Apple computers. The information will also be useful in troubleshooting situations where interface problems may be involved.

The Peripheral Interface Guide contains the following information:

Macintosh, Apple II, Apple III, & Lisa/Macintosh XL

Computers

The first three sections contain the specifications for all built-in interface and interface card connectors for the Macintosh, Apple II, Apple III, and Lisa/Macintosh XL families of computers. Each section covers built-in interfaces first, followed by interface cards. Illustrations at the beginning of each section show the locations of the built-in interface connectors. The guide contains pin numbers, signal mnemonics, signal descriptions, and connector types for all connectors. For interface cards that contain option switches, a table lists the functions of the switches and how they should be set to produce various operating characteristics. Any special information related to an interface is noted. Peripheral connection tables at the end of each section indicate cable requirements for connecting compatible peripherals to each computer.

Peripherals

This section covers Apple peripheral devices. Devices are arranged by category--Laser Printers, Non-Laser Printers, Modems and Communications, and Miscellaneous. The pin numbers, signal mnemonics, signal descriptions, and connector types are listed for each device. Option switch functions and settings are listed, with the default (factory) settings shown in bold type.

Cables

Apple peripheral cables with their pin connections are included here. Each cable chart lists the devices that can be connected with that cable. This section also includes diagrams of the various connectors used.
