Extended Timeshared Operating System

The ETOS (Extended Timeshared Operating System) User's Guide provides comprehensive documentation for users running ETOS on Digital Equipment Corporation PDP-8 computers. It details the system architecture, which enables multiple users to access a central processor via virtual machines. The guide covers essential topics, including:

• System Operation: Getting on-line, login procedures, and account management.
• SCALE Commands: Using the System Command and Login/Logout Executive for tasks like bootstrapping, managing memory, and monitoring virtual registers.
• OS/8 and COS Integration: Procedures for converting and running existing stand-alone programs within the ETOS environment.
• System Functions: Details on various input/output and system commands for advanced assembler programming.

The manual serves as a primary reference for system users to navigate the monitor, handle I/O, and effectively utilize the multi-programming capabilities provided by ETOS.
