- Wallingford is a neighborhood in north central Seattle, lying on a hill above the north shore of Lake Union about four miles from the downtown core. The neighborhood developed quickly during the early 20th century after the establishment of the University of Washington to the east. With trolley tracks laid through the neighborhood as early as 1907, Wallingford is a classic streetcar suburb, typified by its many 1920s era box houses and bungalows. Commercial development is primarily concentrated along North 45th Street where a number of iconic structures stand including the neon “WALLINGFORD” sign, the Wallingford Center, and the original Dick’s Drive-In.

Intel introduced the 8087 chip in 1980 to improve floating-point performance on the 8086 and 8088 processors, and it was used with the original IBM PC. Since early microprocessors operated only on integers, arithmetic with floating-point numbers was slow and transcendental operations such as arctangent or logarithms were even worse. Adding the 8087 co-processor chip to a system made floating-point operations up to 100 times faster.
