I will never make disparaging remarks about DEC. I was a big fan. But I have to call you cold here. DEC was in NO way credited with the first SMP. The Sequent B8000 based on Motorola NS32016 processors was indeed the first commercial SMP. There should still be one in the Smithsonian in fact if they still do that port of the Computer Exhibit. The B8000 was shipping in the 1984 timeframe in pretty large volume.

They usually get it right in academia as depicted in slide 21 here:
