The
Canon FS-5 "Solar Card Scientific Statistical Calculator" was introduced in 1983
and is based on the Toshiba T6824S single-chip calculator circuit known from the
Toshiba SLC-8410 calculator.
This featured FS-5 OHP (Overhead Projector) was modified by Stokes Publishing Company, Inc. based in California and sports a transmissive display. William T. Stokes filed on July 30, 1991 the US Patent Application U.S. Pat. No. 5,035,502 with the title "Transparent calculator for overhead projection" with both the keyboard and the display made from translucent glass and plastics. Don't miss these innovative calculators optimized for teaching purposes and distributes under the label "The Educator®".
In the meantime we were able to locate a more or less identical calculator with the "The Educator®" outfit and some interesting information printed on the backside label.
The Canon FS-5 calculator was replaced soon with the FS-51 model.
