Swords Into Plowshares

There is some controversy in the industry whether Intel or TI made the "first IC." Intel's first IC was for an Asian customer to use in a four-function calculator. Intel's first commercial IC products were static (volatile) RAM chips (like the 3101) which replaced the magnetic cores used even in solid-state computers of the era (1960s). It wasn't until 1971 that Intel marketed the first monolithic microprocessor product, the 4004. Originally designed, as Mr. Anderson said, for the (now defunct) Japanese customer Busicom for a desk calculator. http://en.wikipedia.org/wiki/Busicom Richard- I have no documentation to cite. I once read that the first commercial product that used a microprocessor, was the HP-35 Calculator. According to http://www.hpmuseum.org/hp35.htm, the HP-35 was produced from 1972 to 1975.
