Flandreau is one of four little towns in Moody Co., which is an agri- cultural county. In the 1920 U.S. Cen- sus some 9,742 individuals lived in the county; in 2010 there lived only 6,486 individuals. The population decrease is primarily due to the diminishing need for agricultural laborers. The strange thing is that more families from Kila parish ended up in this special area on the prairie. They grew to be so many that there was a post office named Kila, South Dakota, for a few years around 1900. There was also a cemetery called "Kila Swedish Cemetery."

Why not produce chips with more space for the elec- tronics and thus be able to increase the power greatly, as well as increase their reliability? The antitrust laws also made it possible for Gene Amdahl to use IBM's software. Amdahl Corporation invested more than 40 million dol- lars before they could deliver their first System 470 V/6 computer. It was three times as powerful as IBM's sim- ilar model. Amdahl became a serious competitor of "Big Blue" and succeed- ed in capturing as much as 22% of the market, when several big cus- tomers such as AT&T, General Mo- tors, and NASA bought Amdahl mainframes.
