Modern Mechanix Round-UP

Recently on Modern Mechanix we look at this cool little fish shaped submarine, a 1902 ad for an adding machine called the Comptometer, a 1936 Popular Science piece that explains why we might have another ice age, a dome light for Japanese cops, a comparison of the New York skyline from 1880 and 1930 (and today) as well as a 1977 Hewlett Packard computer advertisement touting their astoundingly inexpensive ECC RAM, just 5 cents (17 cents in 2007 dollars) per byte.
