TOPS-20 KL Model B

This document serves as an installation guide for TOPS-20 Version 5.1 software on new DECSYSTEM-20 KL10 Model B systems, and for updating existing TOPS-20 software on such systems.

The manual outlines a comprehensive installation process, starting with checking the software package (RSX-20F System Floppies A, B, C; TOPS-20 Installation and Distribution Tapes V5; DX20 Microcode Tape, and optional software tapes). It then details the preparation of the DECSYSTEM-20 hardware, including disk formatting and powering up. Key steps involve loading and starting the TOPS-20 monitor, initializing the file system, and creating necessary system directories before restoring bundled software from tape using the DUMPER program.

A significant portion of the guide is dedicated to tailoring the system to specific needs, covering aspects like selecting the appropriate monitor, changing the system name, configuring terminal speeds, defining logical names, setting up magnetic tape drives and line printers, defining the local time zone, directory parameter settings, account validation, performance improvements (latency optimization, working set swapping), scheduler controls (bias controls, class scheduling), file archiving and migration parameters, tape drive allocation, and accounting shift changes.

The document includes a step-by-step procedure for updating a Version 4 TOPS-20 system to Version 5.1 in Appendix A. Additional appendices provide a pocket installation guide for experienced users (Appendix B), instructions for configuring the system for the ARPANET (Appendix C), and procedures for generating a tailored batch and spooling (Galaxy) system (Appendix D). The guide assumes the installer has read the "Getting Started With TOPS-20" manual and is familiar with the "TOPS-20 User's Guide" and "TOPS-20 Operator's Guide."
