ELF OPERATORS GUIDE - VERSION 3.8                      NPD-236      $25.00 
     
This guide describes the Engine Load Facility (ELF) program, which transfers   
and loads NAD Image Binary (NIB) code into Tymnet Engine nodes and slots.  
The manual is intended for operations personnel.  
     
The ELF program runs in an ISIS (Internally Switched Interface System) job 
slot in the Tymnet Engine.  Node code, slot code, or partial slot code,    
which is stored in a NIB file on a TYMCOM-X (PDP-10) in the Tymnet public  
network, is transmitted through one or more gateways to an ELF device in   
the operators network.  From the ELF disk or tape unit the code is loaded  
into a target node or an ISIS slot.
     
This guide describes procedures for doing the following: logging in and    
logging out; using single or multiple gateways; creating; loading, and
dumping code; restarting a node; and using the bootstrap program.  Disk    
and tape procedures are presented, including a description of how to  
initalize an ELF disk.

ENGINE MAINTENANCE MANUAL - JULY 1, 1982               NPD-282      $100.00
     
The Engine is the communciations computer produced by Tymnet to serve any  
of the various roles that nodes play in the Tymnet network.  Although the  
physical size of the cabinets and cardcages differ, the necessary
components of all Engines and Mini-Engines are the same.  Additional circuit   
boards may be added to an Engine to increase its memory or input/output    
(I/O) capabilities, but the type of node that each Engine represents is    
ultimately controlled by the software installed when the node is placed in 
the network.   
     
The Engine Maintenance Manual covers the installation and theory of operation  
of the Tymnet Engine.  The manual is divided into the following sections:  
     
     *  Overview    
     *  Facilities Planning   
     *  Functional Descriptions    
     *  Installation
