IBM 6580 User Manual

PREFACE
This manual contains information necessary to understand the operational theory
and to service the IBM Displaywriter System work station. Service personnel
using this manual must have completed the student education course. This manual
is in ten sections.
The Introduction section summarizes the IBM Displaywriter System. The compo-
nents and features are introduced.
The Operating Instructions section provides an overview of basic operator proce-
dures and activities. Future IBM Licensed Program releases could change the
function of the Displaywriter System. The operator's reference material should
be used for more specific information.
The 25-Line and Large Displays and the Keyboard sections contain operational
theory, service information, adjustments, and removal/replacement procedures.
The Electronics/Power Supply section describes the function of the major compo-
nents of this module and removal/replacement procedures.
The Diskette section contains operational theory, service information, adjust-
ments, and removal/replacement procedures for the Type 1 Drive and the Type 2D
drive (high density/two sided read/write function). The Type 1 Drive is shown
when
the part illustrated is not affected by the differences in the drives.
The Cables/Connectors/Test Points section contains cable and connector test
points, AC wiring diagrams, flow charts, figures showing component locations and
the system grounding schematic. The diskette AC wiring diagrams show the phys-
ical location of the grounds for these voltages.
The Diagnostic section describes the tests and utilities available to aid in
servicing the system and identifying failing components in the system. The dis-
play formats and the printed-outputs are controlled by the software and may dif-
fer from the formats actually displayed. The formats and outputs shown in this
section are samples only.
The Intermittent Problem Diagnostic Approach section is a guide to aid service
personnel in solving intermittent system problems.
