Digital Personal Workstation

The Digital Personal Workstation is a family of entry-level to mid-range workstation computers developed and manufactured by Digital Equipment Corporation (DEC). These workstations are based on the DEC Alpha and Intel Pentium Pro or Pentium II microprocessors. Members of this family can run the Digital UNIX, OpenVMS and Microsoft Windows NT operating systems. The i-Series, based on Pentium Pro, was introduced first, on 23 September 1996.

The Digital Personal Workstation i-Series is based on the Intel Pentium Pro or Pentium II microprocessor and runs Windows NT.

Models include the:

These workstations support either one or two microprocessors and use standard Intel chipsets: Pentium Pro models use the Intel 440FX, Pentium II models suffixed with "i" use the Intel 440BX whereas ones suffixed with "i+" use the Intel 440LX. A superscript "2" suffix indicates a dual processor configuration.

The i-Series has four DIMM slots on its main logic board and supports standard unbuffered or registered 100 MHz ECC SDRAM DIMMs. Using unbuffered memory, the i-Series can support 32 to 512 MB of memory, with registered memory, 64 MB to 1 GB is supported. Unbuffered and registered DIMMs cannot be mixed in the same system. Unbuffered DIMMs have capacities of 32, 64 and 128 MB, whereas registered DIMMs have capacities of 64, 128 and 256 MB.

The Digital Personal Workstation a-Series, code named "Miata", uses the Alpha 21164A microprocessor. Models suffixed with "a" run Windows NT (with AlphaBIOS) whereas models suffixed with "au" run Digital UNIX or OpenVMS (with SRM). At COMDEX 1997, the Digital Personal Workstation 500a was a finalist in Byte magazine's Best of Show award for the best workstation category.
