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
tax planner application was developed in 1982 by Warren,
Gorham & Lamont, Valhalla NY (WG&L) and programmed by Texas
Instruments into a Solid State Software Module. Please notice the © 1983, 1984
date of the module. These modules were probably changed every year due to updates in the tax calculation
process and WG&L introduced in 1985 with the incotax
calculator a more flexible approach.
Dismantling
the tax planner calculator reveals a standard TI-58C
calculator manufactured in Summer 1981. It is one of the earlier models, the
printed circuit board (PCB) of the calculator was manufactured in Canada.
Compare the WG&L tax planner 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.
Warren,
Gorham & Lamont, Valhalla NY was founded in the 1950s, but traces its roots
back to 1882, when Willard Warren started a weekly, the Connecticut Real Estate
Record and Building News (later and still today, The Commercial Record). The
Thomson Corporation acquired Warren, Gorham & Lamont (WG&L) in 1980. For
more than three decades, WG&L was a major information source for finance
professionals in companies of all sizes and industries. The WG&L product
line includes some of the most valued newsletters, journals and treatises in the
legal, tax and accounting fields. WG&L remains one of the most respected
brands in the industry. In 1996, the tax publishing activities of Warren, Gorham
& Lamont were merged with RIA.
