This calculator is a special edition 18R, made
to celebrate the Bicenntenial in the United States in 1976. As such the casing has
been changed to have a red, white and blue theme (see the three-quarter
view on the right---click image to enlarge). The outer casing and the
numbering details are all blue, with bright red keys and a white
upper casing. Other than that, it operates
exactly as an 18R. The calculator was built in Mexico, as the expected
market would, I presume, be limited to the U.S. Which is a pity, as I
prefer this colour scheme to the standard!
This Rockwell '76 has its I.C. labelled 7537 (1975 week 37).
The manual for an 18R is available on the
