Early Friden EC-130 Marketing Brochure - Page 2
This vertically-folding brochure appears to be one of the earliest marketing
brochures announcing the
electronic calculator. Note nomenclature on front panel of calculator showing
model as "Electronic Calculator 130", indicating that the pictured machine
was a pre-production prototype. Production EC-130 calculators had the text
"130 Electronic Calculator" instead.
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.
