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 incotax application was developed
by the Bureau
of National Affairs, Inc., Washington D.C. to calculate
Federal Income Taxes and distributed by Warren,
Gorham & Lamont, Valhalla NY (WG&L).

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.
