The innovative TI-58 was the perfect base for a lot of customized calculators. The idea behind these products was the novelty of the Solid State Software Modules™ with up to 5000 program steps.
The CAL-Q-TAX application was developed by the Bureau of National Affairs, Inc., Washington D.C. in 1984 to calculate Estate and Gift Taxes. Compared to the usual drop-in modules this calculator uses an extender developed by Hand Held Products.
Don't miss the incotax
application using the same extender for the module.
Compare it with a similar product by the insurance companies Agrippina, Allianz, Lloyd, LVM, Nordstern and Victoria or the Bossard screwing joint calculator. Even the French carmaker Chrysler-Simca used the TI-58, don't miss the Chrysler Credicavia. Don't miss the USMC HARRIER flight computer based on the TI-58 calculator, too.
A colorful calculator appeared with the Pool Water Analysis module.
