KS Install 4.1 Feb83

This document is the "TOPS-20 KS/KL Model A Installation Guide," manual number AA-P346A-TM, published in February 1983. It provides step-by-step procedures for installing TOPS-20, Version 4.1 software on new DECSYSTEM-2020 or DECSYSTEM-20, Model A systems, and for updating existing TOPS-20 software on these systems.

The guide covers:

• Installation Preparation: Checking software packages, powering up the system, labeling and mounting disk packs, and checking controller switches.
• File System Creation: Initializing the TOPS-20 file system, including creating home blocks, root directories, various system directories (e.g., SYSTEM, SUBSYS, UETP.LIB), swapping space, and the front-end file system. This involves loading and starting the TOPS-20 monitor.
• System Tailoring: Selecting the appropriate TOPS-20 monitor, changing the system name, setting terminal speeds, defining logical names, configuring magnetic tape and line printer parameters, defining local time zones, directory parameter settings, account validation, performance improvements (full latency optimization, working set swapping), scheduler controls (bias controls, class scheduling), file archiving and migration parameters, tape drive allocation, and creating the LPFORM.INI file.
• Microprocessor File System: Specifically for DECSYSTEM-2020, it details how to build the microprocessor file system.
• System Restarting: Procedures for booting the system from disk.
• Distribution and Update Tapes: Instructions for installing TOPS-20 distribution and update tapes, including unbundled software products.
• User Environment Test Package (UETP): Running UETP to perform a cursory check of the system and its installed software components.
• Appendices: Pocket installation guides for DECSYSTEM-20 and DECSYSTEM-2020, tailoring the system for ARPANET, using a stand-alone disk formatter (KSFORM for DECSYSTEM-2020), generating a tailored batch and spooling (GALAXY) system, and detailed instructions for updating Release 4 TOPS-20 to Release 4.1 on both DECSYSTEM-20 and DECSYSTEM-2020 systems.

The manual notes that specific procedures for DECSYSTEM-2020 are shaded in gray and emphasizes the importance of using correct values for system parameters during installation. It also includes a "Reader's Comments" form for feedback.
