Intel's got Alpha.
[link|http://www.my-esm.com/digest/story/OEG20010626S0043|Here] - from 6/2001. Intel got Alpha when Compaq bought DEC.
HP used to have Itanium, but they mostly [link|http://www.theregister.co.uk/2004/12/16/hp_intel_itanic_shift/|gave that back to Intel] too.
HP doesn't have too much of interest now. :-(
Cheers,
Scott.
