DIGITAL Microsystems Handbook 1985

This document, the "Microsystems Handbook" published by Digital Equipment Corporation in 1985, serves as a comprehensive reference for their 16-bit and 32-bit supermicrocomputers.

The handbook provides detailed information across several key areas:

• Microsystems Family Overview: Introduces the MicroVAX I, MicroPDP-11/73, and MicroPDP-11/23 systems, covering their definitions, markets, number of users, and commonalities (like the Q-bus, hardware, and networks) as well as their architectural differences. It also briefly mentions the MicroPDP-11/SV.
• System Hardware: Outlines the basic components including CPU modules (KD32-A, KDJ11-B, KDF11-B), system chassis and enclosures (floorstand, tabletop, rackmount), backplanes, power supplies, control panels, and I/O distribution panels. It also covers various system configurations.
• System Options: Describes a wide range of available options to enhance system performance and functionality, such as memory modules, floating-point processors, various storage devices (fixed and flexible disks, cartridge tapes), communication interfaces (asynchronous, synchronous, Ethernet), and peripheral devices like video terminals, printers, and modems.
• System Software and Layered Products: Details the operating systems available for MicroVAX (MicroVMS, ULTRIX-32m, VAXELN) and MicroPDP-11 (RSX-11 family, RSTS family, MicroPower/Pascal, ULTRIX-11, RT-11, CTS-300, DSM). It also covers high-level programming languages (e.g., Ada, BASIC, C, COBOL, FORTRAN, PASCAL), information management software, productivity tools, and communications software.
• Networks: Explains Digital's Network Architecture (DNA), various network configurations (standalone, network-connected), different types of communication links (Ethernet, asynchronous, synchronous), and the network software that enables these connections.
• Architecture Summary: Provides a technical overview of the MicroVAX I and MicroPDP-11 architectures, detailing address space, memory management, registers, addressing modes, data types, and instruction sets.
• Appendices: Include in-depth technical descriptions of the Q-bus, information on the PDP-11/23-PLUS, site preparation and installation guidelines, details on customer services, and a list of additional documentation.

In essence, this handbook serves as a comprehensive technical and operational guide for Digital's supermicrocomputer systems, their hardware, software, networking capabilities, and support services, aimed at helping users understand, configure, and expand these systems.
