PCI Graphics Accelerators for AlphaStation Systems

HIGHLIGHTS

o  New ZLXp-E graphics accelerator family for AlphaStation systems

o  Best 2D and 3D vector price/performance in the industry

o  Supported under DEC Open3D for DEC OSF/1, DEC Open3D for OpenVMS AXP, and
   ZLXp-E Support Services Software for Microsoft Windows NT software

PRODUCT DESCRIPTION

The ZLXp-E graphics accelerators are single slot PCI-based modules for 2D
and 3D graphics acceleration. The ZLXp-E1 module is 8 bits per pixel,
offering 256 simultaneously displayable colors, and is designed for
two-dimensional applications. The ZLXp-E2 graphics accelerator offers 24
bits per pixel for true color image display, and 4 overlay planes. The
ZLXp-E3 module has 24 bits per pixel, 4 overlay planes, and a full 24-bit Z
buffer for solid model rendering.

BENEFITS

The ZLXp-E1 graphics accelerator, with its excellent 2D performance, is an
ideal fit for a wide variety of applications. Users doing document creation
and editing, low-end mechanical CAD, or any 2D graphics oriented application
will be able to realize immediate benefits using the ZLXp-E1 graphics
module. The ZLXp-E2 graphics accelerator is ideal for image processing,
medical imaging, and desktop publishing due to its true color capability. In
addition, the ZLXp-E2 graphics accelerator can be configured to run 8 bits
double buffered with a 16-bit Z buffer, a key configuration for MCAD
applications. The ZLXp-E3 graphics accelerator, with its 24-bit Z buffer is
ideal for mechanical CAD and computer aided molecular design.

AVAILABILITY AND ORDERING

The PBXGA-AA, PBXGA-BA, PBXGA-CA, and PBXGA-AN PCI Graphics Accelerators for
AlphaStation systems are available now. All ZLXp-E configurations require a
DEC Open3D license or ZLXp-E Support Services Software license.
