Early Friden EC-130 Marketing Brochure - Page 4
This vertically-folding brochure appears to be one of the earliest marketing
brochures announcing the
Friden EC-130
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.
