DECpc represented a broad range of desktop computers, laptops, servers, and workstations marketed by Digital Equipment Corporation. While the majority of these systems incorporated x86 CPUs, the APX 150 stood out by utilizing DEC's exclusive Alpha processor. This product series signified DEC's major venture into the IBM PC compatible arena. The company promoted these machines as competitively priced options boasting advanced features compared to their earlier models. Certain desktop variants were produced in collaboration with Olivetti S.p.A. and Tandy Corporation.
