People sometimes think that the market caused the Alpha to fail. Really, it was Intel. They wanted Itanic to succeed so much that they made a deal with HP to end the Alpha prematurely, even though demand for Alpha systems was high.
Even after HP announced that the Alpha would stop being developed, Alphas were being sold as a high end systems for all sorts of uses and had many entries in the Top 500List of supercomputers - Alpha systems were four of the top ten on the planet in November, 2002, which was after HP announced they wanted to transition from Alpha to Itanic.
My AlphaServer DS25 is beautiful hardware. Everything in the machine is manufactured to a standard we just don't see any more.
