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.

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.
