OVERVIEW
System Design
Overview
The Hewlett-Packard Vectra
PC
is
designed
to
provide a
wide
range
of
system solutions
for
the computing needs
of
today. The
system architecture supports a wide range
of
expansion
capabilities, and it
is
compatible
with
a broad line
of
industry
standard software and hardware.
The heart
of
the
HP
Vectra
PC
system
is
the Intel 80286
microprocessor. The 80286
is
one
of
the most powerful
microprocessors available today, yet
it
maintains a high degree
of
compatibility
with
8086/8088 microprocessor
used
in many
industry standard personal computers. The
HP
Vectra
PC
owes
much
of
its power and flexibility
to
the inherent capabilities
of
the
80286.
The
basic
HP
Vectra
PC
systems contain either 256 Kbytes
or
640
Kbytes
of
internal RAM.
The
256 Kbyte memory may
be
expanded
up
to
640 Kbytes
without
using internal expansion cards. All
HP
Vectra
PC
systems come
with
64
Kbytes
of
system firmware. An
additional 192 Kbytes
of
firmware may be added
in
modules,
bringing the total
to
256 Kbytes
of
ROM.
The
HP
Vectra
PC
has
mounting space and
power
connections
for
three internal disc drives. Three different disc drive units are
available: a 360
KB
Internal Flexible
Disc
Drive, a 1.2 MB Internal
Flexible
Disc
Drive, and a 20 Mbyte hard disc drive. The hard disc
drive may
be
installed along
with
two
flexible discs. The flexible
drives may
be
of
the same type, or a 360
KB
and a high-capacity
(1
.2
MB)
drive may
be
installed together. Another option could
be,
two
hard disc drives installed
with
one flexible disc drive.
