The innovative TI-58 was the perfect base for a lot of customized calculators. This one was used end of the 70th 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.
