This manual was written to provide information about the Edinburgh
Advanced Personal Machine. 
It was achieved grouping  together and restructuring all the information 
available
on the subject.  Hopefuly, as you go along reading it, you
will discover more about the system and get familiar with its principal
components.  Since it is a working manual, it is subject 
to revision and change. Users are therefore advised to check that they have the
latest version when working with the APM.

@PrefaceSection(INTRODUCTION)

The Edinburgh Advanced Personal Machine is a  
Edinburgh University development which has taken as a target the provision 
of the following  features:
@Begin(Itemize)
Standard and simple interconnection of system 
components
 
Multiple layers of system modularity
 
Flexibility
 
Enhancement of performance through addition of new
modules into an existing structure
 
Ease of incorporating new technological developments
 
Ease of experimentation and system reconfiguration
 
Short development time for the introduction of new 
models
@End(Itemize)
The aim in practical terms has been to construct a high-performance 
network-based modular computer system which can be easily tailored to specific
applications.

The computer itself is modular at the board level.  An individual machine
incorporates a selection of compatible processor and memory boards.  A key
factor in the flexibility of the system is the adoption of a philosophy of
functional distribution, with a general-purpose internal bus providing the
internal communication between function-specific boards.  The bus  has been
designed to have sufficient capability to support a variety of existing
and forthcoming processors and devices.

The principal role of thesystem is as a high-performance single-user workstation
which is a personal computer in the special sense that it is individually
tailored to suit the computing requirements of its users.
