DECpc was a wide-ranging family of desktop computers, laptops, servers, and workstations sold by Digital Equipment Corporation. The vast majority in the family are based on x86 processors, although the APX 150 uses DEC's own Alpha processor. The line was DEC's first big break into the IBM PC compatible market.[1]
