Those chips are from DEC machines. The far right one is from a DEC Alpha machine, very fast for its time when it came out.
While I was researching to find out what e-waste was all about I found a site that collects CPUs. Didn't see those exact CPUs in his photos. Maybe he would be interested at a price greater than scrap. I'd email him a photo and see what he has to say.
