This Digital Equipment Corporation system had a 32-bit processing architecture, employed complex instruction set computer processors (CISC) and ran on an OpenVMS operating system. The change was made to provide enhanced performance and a more modern tool set for UDP’s customers. When DEC stepped into the 64-bit computing space in 1991, UDP took advantage of the new AlphaServer line, designed around reduced instruction set computer processors (RISC) to support its applications on both hardware platforms.
