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 BA II Plus introduced by Texas Instruments in 1991 developed itself to a very successful business calculator. The one to one replacement from Stokes Publishing Company is this Business overhead calculator.

Overhead™ Calculator is a trademark of Stokes Publishing Company, Inc.
