Introduction To The Dimension Service Manual - North Star DIMENSION Service Manual

INTRODUCTION TO THE DIMENSION SERVICE MANUAL
The North Star DIMENSION is a versatile, fast, and reliable computer
system that incorporates contemporary system design, imaginative use of
electronic circuitry and components, and rigid manufacturing quality
control. This service manual attempts to follow in these traditions.
A service manual that attempts to be all things to all people is asking for
trouble. There are computer users who simply want to install their own
systems; technicians who have only the responsibility of maintaining the
equipment; engineers who need to understand the host-system in order to
design hardware peripherals; and programmers who may wish to create
alternative operating systems or application packages. This manual is not
written for all of you.
If you are a system owner / user who wants to install your own equipment,
we recommend reading the DIMENSION System Manual. It contains
abbreviated hardware and operating system installation instructions that
are tailored especially for you.
If you are a technician who needs a manual to help speed your
troubleshooting, diagnosis, and repair of problems, this manual is for you.
The manual is specifically designed for the field technician who must get
in, fix the problem, and leave quickly. The manual contains no theories of
operation, specifications, extensive parts lists or schematics. It does
contain diagnostic charts, troubleshooting steps, and
removal/replacement/adjustment procedures. The DIMENSION Service
Manual is the field-accompaniment to the DIMENSION Technical Manual.
If you are an engineer who needs to know anything and everything about
DIMENSION hardware, we recommend that you refer to the DIMENSION
Technical Manual .
It contains specifications , theories of operation,
schematic diagrams , timing diagrams , and parts lists related to the system
and each of its components.
If you are a programmer , and your task is to create alternative operating
systems or application programs for our computer , we recommend reading
the DIMENSION Programmer's Notebook . This manual contains only the
very specialized information required by a programmer.
