As mfro said, Alpha. DEC never manufactured MIPS processors; it bought them from (amazingly enough) MIPS Inc, and used them from 1989 in DECstation RISC boxes.
DEC launched its own RISC architecture, Alpha, in 1992. I'm pretty sure DECstation was discontinued by 1995. DEC never did deliver OSF/1, its next-generation Unix, to DECstation despite promising to do so.
