The AlphaStation 255/233 and 255/300 Desktop Workstations comprise a
family of entry to mid-range PCI-based Alpha Universal Client systems. The
AlphaStation 255 family delivers premium performance while providing access
to thousands of applications running on the DIGITAL UNIX, OpenVMS or
Windows NT Workstation operating systems.
The AlphaStation 255/233 system uses the Alpha 21064A microprocessor
running at 233 MHz with performance measuring 4.27 SPECint95 and 5.09
SPECfp95. This entry level to low end system is ideal for running 2D CAD,
CASE, Multimedia and Software Development applications.
The AlphaStation 255/300 system also uses the Alpha 21064A microprocessor,
but at a higher speed of 300 MHz and with performance measuring 4.23
SPECint95 and 5.81 SPECfp95. This mid-range system is optimal for working
with 2D CAD and 3D CAD applications.
All AlphaStation 255 systems come packaged in a compact enclosure, with
capacity for up to 512 Mbytes of parity memory, 128-bit wide memory bus, four
storage slots, four option slots (2 PCI, 1 PCI/ISA combination, 1 ISA) and a
1 Mbyte secondary cache. The high performance PCI I/O bus, running at 132
Mbytes/second, provides expansion for options such as high-performance
graphics, networking, and SCSI adapters without the need for additional tabletop
options or expansion boxes. All systems support a wide variety of industrystandard
peripherals and PCI/ISA options. Other standard features include
integrated Twisted Pair Ethernet (ThinWire is optional), stereo-quality audio,
external ports for serial/parallel communications, and external SCSI.
