The innovative TI-58 was the perfect base for a lot of customized calculators. This one was used end of the 70^th by engineers to calculate screwing joints. 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 Swiss Bossard company and programmed into the modules by Texas Instruments.

You ever dreamed of a TI-58 with more memory for both data and programs? Here it is! This calculator combines the electronics of the TI-58 with the huge memory of the TI-59.

Compare it with a similar product by the insurance companies Agrippina, Allianz, Lloyd, LVM or Nordstern or the CAL-Q-TAX calculator.

Another approach to customize a calculator could be found in the Goulds Pumpulator.
