computers were initially designed as calculating machines. The
first fully electronic computer, the ENIAC, was built by the
U.S. military during World War II to produce ballistics tables
for artillery in battle. Computers then were clumsy, hulking
devices Ð the ENIAC had 18,000 vacuum tubes, and measured 50
x 30 feet Ð that did calculations for scientific research. Only
a handful of scientists considered the possibility of personal
computing for creative purposes by non-specialists.
