11SIM Reference Manual

A program that simulates a Digital Equipment Corporation PDP-11 computer and many of its peripherals on the AI Laboratory Time Sharing System (ITS) is described from a user's reference point of view. This simulator has a built in DDT-like command level which provides the user with the normal range of DDT facilities but also with several special debugging features built into the simulator. The DDT command language was implemented by Richard M. Stallman while the simulator was written by the author of this memo

PEEK

PEEK is a utility program designed to operate under the ITS time sharing system. It enables a user to monitor a variety of aspects of the time sharing system by providing periodically updated display output or periodic printer output to teletype or line printer. just what information is being presented to the user is controlled by PEEKs information mode. The available modes are listed in section 3 below. Section 5 describes how PEEK determines which device to output on. Section 2 describes, in general, how the user can input commands to PEEK

U.T.: Telnet Reference Manual

UT is a user telnet program designed to run under the ITS time sharing system. It implements the relatively recent ARPA network negotiating protocol for telnet connections

ITS Status Report

ITS is a time-shared operating system designed for the Artificial Intelligence Laboratory DEC PDP-10/PDP-6 installation and tailored to its special requirements. This status report described the design philosophy behind the ITS system, the hardware and software facilities of the system implemented with this philosophy, and some information on work currently in progress or desirable in the near future

PEEK and LOCK

This memo describes two small utility programs that are of assistance in using the ITS 1.4 (see A.I. 161, MAC-M-377) time sharing system. LOCK performs miscellaneous utility functions while PEEK displays, with periodic updates, various aspects of the time sharing system's status

Lock

LOCK is a miscellaneous utility program operating under the ITS system. It allows the user to easily and conveniently perform a variety of infrequently required tasks. Most of these relate to console input-output or the operation of the ITS system
