The California based company Stokes Publishing Company, Inc. distributes under the label "The Educator®" calculators optimized for teaching purposes. William T. Stokes filed already July 30, 1991 the US Patent Application U.S. Pat. No. 5,035,502 with the title "Transparent calculator for overhead projection".
Both the keyboard and the display are made from translucent glass and plastics. Using a simple overhead projector the teacher could demonstrate easily the function of a calculator.
The Educator Basic emulates the Texas Instruments TI-108 with basic four functions, automatic constants in all four functions, percent, square root, and change sign keys, add to and subtract from memory keys, and clear last entry or all entries.
A similar calculator called Basic II emulates the TI-106.
The design of the Educator Basic was enhanced in 1997, view the latest edition here.
