Digital Equipment Corporation
Rolls up to Hewlett Packard Enterprise
The Alpha architecture was the fastest processor line in the world for much of the 1990s. DEC was acquired by Compaq in 1998, Compaq by HP in 2002, and the enterprise business became HPE in 2015: three hops from the supplier that shipped the machine to the ticker that carries it today.
