ETOS System Hardware Installation or Modification

This document, Chapter 2 of the ETOS system guide, provides detailed instructions for installing and modifying the system hardware necessary to operate ETOS. It covers procedures for booting various disk packs (RK05, System Industries) under different processor configurations (PDP-8/E, PDP-8/A), formatting disk packs using utility programs like RKLFMT and 3040, and performing backup operations. Furthermore, the text details the hardware requirements for enabling timesharing, configuring system clocks, and setting up terminal characteristics (parity, stop bits, filler characters) to ensure optimal ETOS performance.
