Etos

This document serves as a comprehensive manager’s guide for the ETOS (Extended Time Shared Operating System) Version 5B. It details the administrative functions necessary for operating the system, including installation, hardware requirements, disk layout management, memory configuration, and user account creation.

Because the guide covers critical operations such as system startup, shutdown, and backing up data—which could lead to system data loss if improperly executed—it is explicitly noted that this material is for the system manager and should not be distributed to general users. The manual also provides detailed technical specifications for both "real" (stand-alone) and "virtual" OS/8 and COS environments, along with extensive tables listing supported software, resources, and configuration conventions.
