Dec Alpha
Alpha was a revolutionary CPU architecture. Designed by DEC and launched in 1992, it was intended as a workstation and server platform that would remain stable for decades, through successive generations. On paper, Alpha was brilliant. Unfortunately, although the product was sound, the strategy wasn’t.
Almost as soon as Alpha processors appeared, businesses began to move away from workstations and multi-user servers in favour of increasingly cheap and capable Windows PCs. Microsoft shifted its focus to this market and began to phase out support for Alpha, leaving the platform – and its its manufacturer – to serve a shrinking niche market. DEC faltered, and ended up being bought by HP, which halted development of Alpha processors in 2004.
