PREFACE
The
HP
Vectra
Technical
Reference
Manual
is
divided
into
two
volumes. Volume 1
is
focused on
the
hardware. It
is
intended
for
use
by design engineers, system programmers,
or
any other
person
who
wishes
to
know
the
HP
Vectra
PC
at a very detailed
technical level.
This volume consists
of
a hardware description
of
the
processor
board and the components
of
the board. A basic capability
description and a system interface description
is
given. Included in
the
description
of
the processor board are: memory and I/O
address maps, backplane
I/O
pin assignments and signal
descriptions, connectors, and subsystem-to-system register
definitions.
Also included
is
a description
of
the accessory cards
that
append
to
the system through the backplane I/O channels. The emphasis
of
the accessory card description will be
the
interfaces
the
cards
have
with
the system. The information
is
limited
to
the
port
addresses, pin assignments and signal definitions, register
definitions, and jumpers.
This manual also includes: a glossary, a bibliography, and an
index. A glossary
is
given
for
HP-specific term clarification. The
bibliography should
be
used
to
aid
the
engineer
or
the
programmer
in
search
of
detailed data on a specific chip
or
circuit.
Hewlett-Packard defines some specifications
for
the
IC's,
therefore, some parameters may vary. The index
is
an alphabetical
listing
of
important subjects. It
is
used
to
refer the reader
to
the
appropriate page(s)
for
a listed subject.
