Alpha, originally known as Alpha AXP, is a 64-bit Reduced Instruction Set Computer (RISC) instruction set architecture (ISA) developed by Digital Equipment Corporation (DEC), designed to replace the 32-bit VAX Complex Instruction Set Computer (CISC) ISA and its implementations.
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, BSD UNIX (NetBSD, OpenBSD and FreeBSD up to 6.x) and L4Ka::Pistachio.
