innovative TI-58 was the perfect base for a lot of
customized calculators. This one was used from 1980 by Sanilabel Belgium CV - a leading
construction company in Europe - to calculate the necessary amount of energy to
heat flats or houses considering the local parameters like for instance room
space, size of walls, number of windows and more.
The idea behind these products was the novelty of the Solid State Software Modules™ with up to 5000 program steps. This software was written by the SW-engineers of the EDF SA company and programmed into the modules by Texas Instruments.
The customized keyboard hides most functions available on the standard TI-58 and allows only access to the basic calculation functions and the programmed functions of the EDF module.
Dismantling the calculator reveals a standard TI-58 calculator manufactured in April 1980.
An almost identical Energy Calculator was sold by the EDF Group in France.
Compare it with a similar product by the insurance companies Agrippina, Allianz, LVM, Lloyd, Nordstern and Victoria or the CAL-Q-TAX calculator.
Another approach to customize a calculator could be found in the Goulds Pumpulator.
