About: DEC Alpha   Sponge Permalink

An Entity of Type : dbkwik:resource/vrmnh2X4rmt9DC4U88nL7A==, within Data Space : dbkwik.org associated with source dataset(s)

Operating systems that supported Alpha included OpenVMS (previously known as OpenVMS AXP), Tru64 UNIX (previously known as DEC OSF/1 AXP and Digital UNIX), and Windows NT (until 4.0 SP6 and Windows 2000 RC1). Open source operating systems that run on the Alpha are Linux (Debian, Gentoo Linux and Red Hat Linux), BSD UNIX (NetBSD, OpenBSD and FreeBSD up to 6.x) and L4Ka::Pistachio.

abstract
  • Operating systems that supported Alpha included OpenVMS (previously known as OpenVMS AXP), Tru64 UNIX (previously known as DEC OSF/1 AXP and Digital UNIX), and Windows NT (until 4.0 SP6 and Windows 2000 RC1). Open source operating systems that run on the Alpha are Linux (Debian, Gentoo Linux and Red Hat Linux), BSD UNIX (NetBSD, OpenBSD and FreeBSD up to 6.x) and L4Ka::Pistachio. The Alpha architecture was sold, along with most parts of DEC, to Compaq in 1998. Compaq, already an Intel customer, decided to phase out Alpha in favor of the forthcoming Hewlett-Packard/Intel Itanium architecture, and sold all Alpha intellectual property to Intel in 2001, effectively killing the product. Hewlett-Packard purchased Compaq later that same year, continuing development of the existing product line until 2004, and promising to continue selling Alpha-based systems, largely to the existing customer base, until October 2006 (later extended to April 2007).
