Like Microsoft, Intel has grown fat and sleek on the back of the IBM PC, but like Microsoft it nearly didn't happen. Although this is where the first microprocessor was designed — the famous 4004 — the company had little time for it and did not consider it a successful product. It also fell out with the chief hardware designer, Frederico Faggin, who went off to found Zilog and produce the Z80. But everyone fell out with everyone all the time back then, and now everyone has prizes.
Real-life visiting potential: 8/10. Santa Clara is ghastly, but the Intel Museum should be on the to-do list of all true silicon life forms.
