The Digital Equipment architecture that was the company's principal product line prior to the Alpha. VAX was enormously successful in Digital's traditional engineering and scientific customer base and, more significantly, enabled Digital to penetrate the commercial data-processing and office-automation markets. In 1999, Compaq Computer — which acquired Digital Equipment in 1998, and was itself acquired by Hewlett-Packard in 2002 — announced plans to phase out the VAX platform in favor of Alpha system products.
The VAX is a computer platform developed by Digital. Its plural is VAXen. VAXen are large expensive machines that were once quite popular in large businesses; today modern UNIX workstations have all the capability of VAXen but take up much less space. Their OS is called VMS.
Virtual Address eXtension (refers to Digital's 32 bit processor technology) all early 700 series machines could run PDP-11 code in compatibility mode (this was done to allow customers to migrate from PDP to VAX without rewriting their software VAX-11/780 (the architecture reference platform. "One VUP" still means "one VAX-11/780") VAX-11/750 VAX-11/730 http://en.wikipedia.org/wiki/VAX http://h18002.www1.hp.com/alphaserver/vax
n. Acronym for virtual address extension. A family of 32-bit minicomputers introduced by Digital Equipment Corporation in 1978. The VAX, like the later 68000 microprocessor, has a flat address space and a large instruction set. The VAX was highly favored within the hacker community but has been superseded by microprocessors and RISC workstations. See also flat address space, instruction set, microprocessor, minicomputer, RISC.
VAX is a 32-bit computing architecture that supports an orthogonal instruction set (machine language) and virtual addressing (i.e. demand paged virtual memory). It was developed in the mid-1970s by Digital Equipment Corporation (DEC). DEC was later purchased by Compaq, which in turn was purchased by Hewlett-Packard.
This program plays/records audio from modem in 'raw modem' format and extracts/acts on DLE-shielded codes such as DTMF, busy, etc. It was designed as the 'key' piece of a bash-script based voicemail system.
