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.
