Hoffmann-La Roche, a Swiss multinational healthcare company, launched in 1981 during a press conference in a New York City the Fitness 3 program as segment of the Vitamin Education Program. The three parts of the Fitness 3 program were fitness, nutrition, and health. Fitness 3 was established when Hoffmann-La Roche received the results of a national/exercise survey conducted for them by a large market research firm. The study indicated that Americans have a great deal of interest in fitness and quality of life. However, their perceptions of the benefits and the meaning of exercise, a good diet, and health habits differ greatly from actual behavior in these areas.
Hoffmann-La Roche applied on July 13, 1981 for a trademark for the phrase FITNESS 3. We assume that the FITNESS 3 MICRO COMPUTER was related to the trademark.
Dismantling the featured FITNESS 3 MICRO COMPUTER manufactured in November 1983 by National Semiconductor in Taiwan reveals a printed circuit board (PCB) marked with 103C-12. Obviously a reference to the NS103A Data Checker introduced in 1980 and its sibling Novus Electronics NS101A sporting just one Memory.
Please find an overview of the
PCB-Marks we discovered
so far on Account Manager calculators.
Comparing the FITNESS 3 MICRO COMPUTER with the NS101A reveals two basically identical products with just cosmetic differences: The ,  and  keys correspond to the [DEP/M+], [CHK/M-] respectively [BAL/MR] keys. The red [%] key is labeled CALORIC RATIO with the FITNESS 3 MICRO COMPUTER and even the [DS] key to toggle between two entry modes is still present:
|• Indicator (--) Floating decimal with manual insertion of the decimal using the [.] key
• Indicator (AM) Add mode with the decimal automatically put in the dollars and cents position (0.00
The featured FITNESS 3 MICRO COMPUTER reveals a
clean design centered around a NEC uPD1831G single-chip calculator circuit
powered by two LR43 batteries. We located the uPD1831G chip in the Texas
Instruments TI-18 calculator, too.
