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 TI-30Xa SE introduced by Texas
Instruments in 1995 and updated in 1999 developed itself to a very successful school
calculator. The one to one replacement from Stokes Publishing Company was this
Scientific Plus overhead calculator.
This wonderful designed Scientific Plus replaced the previous Scientific Plus introduced already in 1995.
Please notice the ©1997 SPC printed on the calculator shown on the package.
