Early Friden EC-130 Marketing Brochure - Page 4
This vertically-folding brochure appears to be one of the earliest marketing
brochures announcing the
electronic calculator. Note that this page states that the weight of the
calculator is 50 pounds. Actual production EC-130s weighed in eight pounds
lighter at 42 pounds.
Sincere thanks to the sons of Clifford Rueff(Eugene, Christopher, and Roger Rueff) for donation of this document, and a large
collection of early Friden calculator materials to the Old Calculator Museum.
