Intel 8087 Math Coprocessor (1980)
The floating-point coprocessor that the original IBM PC had an empty socket for.
Announced in 1980 to pair with the 8086 and 8088, the 8087 ran floating-point math in parallel with the main CPU. Sales jumped after the 1981 IBM PC included a coprocessor socket. Only software written for the x87 instructions benefited, mainly spreadsheets, CAD and engineering tools.
