HPVECTRA PC
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.
