The Kenbak-1, the first personal
computer, advertised for $750 in Scientific American. Designed by John
V. Blankenbaker using standard medium-scale and small-scale integrated
circuits, the Kenbak-1 relied on switches for input and lights for
output from its 256-byte memory. In 1973, after selling only 40
machines, Kenbak Corp. closed its doors.
