I know. I was trying to be snarky. I still have an AlphaServer that I boot up from time to time to relive the glory days. Alphas were too good to be allowed to continue. I understand that intel won in the marketplace and DEC did some pretty stupid things, but I would be happier if they won with products that weren't so crappy.
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.
