Overview
HP Vectra 500 Series PCs are Pentium-processor, ISA/PCI-based PCs,
housed in desktop and minitower casings. The series is targeted at the Small
Business Small Office (SBSO) market.
System Board
There are three system board options for models 520 and 525. The three
options can be referred to as Type A, Type B and Type C.
Type A (part number D4051-63001) is a new system board which
incorporates a technology known as Unified Memory Architecture (UMA).
Using UMA, there is no dedicated video memory. Instead, a portion (1 MB or
2 MB) of main memory is shared as video memory. Refer to Chapter 2 for
more information about this system board.
Type B (part number D3657-63001) is the same as the system board used in
the Q1 1996 collection (models 510 and 515).
Type C (part number D3661-63001) is used for one product only. This board
is the same as the Type B board but without the onboard video controller
and memory. Video control and memory is obtained using a Matrox MGA
Millennium video card.
Backplane
There are two backplane options for models 520 and 525—one for the
desktop and one for the minitower. The two backplanes are the same as
those used in the Q1 1996 collection (models 510 and 515).
Case
There are two casing options for models 520 and 525—one for the desktop
and one for the minitower. The two backplanes are the same as those used
in the Q1 1996 collection (models 510 and 515).
Air Flow Guide
With high speed processors (166 MHz and above), an air flow guide is
required to help the fan dissipate the heat from the processor. On desktop
models, a special power supply unit integrates the fan over the processor.
