The innovative TI-58 was the perfect base for a lot of customized calculators. This one was used end of the 70th by insurance agents of the German LVM company. 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 LVM company and programmed into the modules by Texas Instruments.

Compare it with a similar product by the insurance competition Agrippina, Allianz, Lloyd, Nordstern and Victoria or the CAL-Q-TAX calculator. Even the French carmaker Chrysler-Simca used the TI-58, don't miss the Chrysler Credicavia.

We know five different approaches of the module expansion:

Standard modules like the Master Library use only the small sticker
   above the A,B,C,D, and E keys.
Other modules like this LVM Insurance calculator make use of a colorful keyboard mask.
Customized calculators like the USMC AV-8C calculator or insurance calculators
   sold by Allianz and others use special keyboard arrangements.
The CAL-Q-TAX calculator uses an extender instead the usual drop-in modules.
The Kodak Q-700 Program Adapter makes use of a snap-on cover with
   an individualized printing.

Dismantling the LVM Insurance calculator reveals a standard TI-58 calculator manufactured in October 1980.

The calculator was available till the year 1983.
