WARNING: This equipment generates, uses, and can radiate radio frequency
energy and if not installed and used in accordance with the instructions manual,
may cause interference to radio communications. It has been tested and found to
comply with the limits for a Class A computing device pursuant to Subpart J of
Part 15 of FCC Rules, which are designed to provide reasonable protection
against such interference when operated in a commercial environment. Operation
of this equipment in a residential area is likely to cause interference in which case
the user at his own expense will be required to take whatever measures may be
required to correct the interference.

Preface
This manual provides detailed instructions for installing and operating a WD800 or WD800A mass
storage system. It also contains programming information for those users who write their own
input/output routines. The information in this manual is divided into five sections and three
appendixes as follows:
Section
NOTE
The WD800 and WD800A operate in a similar manner. They primarily
differ in the storage capacities of the Winchester disk drives. Unless
noted otherwise, when this manual refers to the WD800, the
information applies to both the WD800 and the WD800A disk units.
1 WD800 System Kit Description -Briefly describes the features and major components
of the WD800 system.
2 TILINE Peripheral Bus Interface (TPBI) -Describes the operation of the TPBI and
explains the procedures for unpacking, installing, and programming the TPBI board.
3 WD800 Chassis Installation and Programming -Provides site requirements and step-
by-step instructions for unpacking, installing, and programming the chassis.
4 WDBOO System Kit Installation -Explains the kit-level installation of the WD800
system, system self-tests and diagnostics, and procedures for system checkout.
5 Operation -Describes the operator's use of the system.
Appendix
A Fault Analysis -Provides information for use in analyzing system fault conditions.
B TPBI System Command Trace Feature -Provides operating instructions for using the
TPBI command trace in troubleshooting system problems.
C Sample 990 Device Service Routines -Provides instructions and sample device service!
routines (DSRs) for users who write theirown input/output routines.
