The Business Analyst-I was introduced 1979 as a facelifted low-budget version of the Business Analyst.
The rechargeable battery pack was replaced by a simple 9V cell and the usage of a metal key plate gave a more modern appearance. Battery consumption of the Business Analyst-I was horrible, marketing guys from TI invented the after market sales of "Rechargeable Kits" RK2. They used two AA-cells and a step-up converter to generate the 9V of the calculator.
The next step in cost reduction was the usage of the simple, black keys of the TI-30 and a printed key plate. Have a view of the Money Manager.
Based on the technology of the Business Analyst-I a custom specific business calculator was created. Have a look on the Goulds Pumpulator.
Later in production, about in September 1981, the metallized TI logo was replaced with an un-metallized one. View here the Business Analyst-I w/o chrome.
Don't miss the rare TI-30/super manufactured for Koh-I-Noor Hardtmuth.
