Microsystems Options

This document, "Microsystems Options" (Order Number EK-192AA-MG-001, dated October 1988) from Digital Equipment Corporation, serves as a comprehensive guide for reference, configuration, and maintenance of various hardware options supported by MicroVAX and MicroPDP-11 systems. It is primarily intended for Digital Field Service personnel and qualified self-maintenance customers.

The guide covers a wide array of options, including:

• Analog I/O devices (Digital-to-Analog and Analog-to-Digital Converters, Analog I/O Modules)
• Communication controllers and multiplexers (Asynchronous and Synchronous types, Ethernet Interfaces, Modems)
• Programmable Real-Time Clocks
• Printer Subsystems
• Various Disk Drives (fixed, removable, diskette drives) and their associated Controllers (Disk Controllers, Expander Modules, Digital Disk Subsystems)
• Tape Drive Subsystems

For each supported option, the document provides detailed information, typically including:

• Ordering Information: Module numbers, cabinet kits, and associated components.
• Operating System Support: Listing compatible versions of MicroVMS, VMS, RSX, ULTRIX, and VAXELN.
• Diagnostic Support: Details on MicroVAX Diagnostic Monitor (MDM) and XXDP, including power-up self-tests, LED indicators, and troubleshooting using loopback connectors.
• DC Power and Bus Loads: Electrical consumption specifications.
• Description: An overview of the option's function and features.
• Configuration: Crucial details on setting unique device addresses (Control and Status Register - CSR) and interrupt vectors using jumpers or DIP switches. It distinguishes between fixed and floating addresses/vectors and emphasizes the use of the CONFIG program within the MicroVMS/VMS SYSGEN utility as the primary method for determining these settings, with manual tables provided as a fallback.
• General Maintenance Information: Including field replaceable units (FRUs).

The document also provides an overview of general ordering procedures and module configuration principles, and includes an appendix listing related documentation.
