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 TI-30Xa SE introduced by Texas Instruments in 1995 developed itself to a very successful school calculator. The one to one replacement from Stokes Publishing Company is this Scientific Plus overhead calculator.
The design of the Scientific Plus was enhanced in 1997, view the latest edition here.
