ALPHASTATION 255/300 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 180 SPECint92 (3.80
SPECint95) and 210 SPECfp92 (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 215
SPECint92 (4.51 SPECint95) and 245 SPECfp92 (5.71 SPECfp95). This midrange
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.
The AlphaStation 255 Family workstations come in a new design and color
enclosure. Only peripherals in the new color scheme and design can be ordered
with the new systems. Customer-installable chip upgrades provide investment
protection to all AlphaStation 255
