stylish Business Card looks different to all but one Texas Instruments products you
know. It is the rare sibbling of the TI-1760 DataCard
introduced in 1979. Main difference is the additional row of keys and the
2ND-key never found in a "Basic" calculator. A deeper exploration of
the keyboard reveals some financial keys as second function of the operation
keys, a layout unknown with calculators developed by Texas Instruments.
Dismantling the Business Card reveals a design very similar to the TI-1760 DataCard. No doubts that this cutie uses a calculator chip of the TP0320 family instead the TP0311 of the Basic-line. You know the TP0320 calculator chip from products like:
|TP0320 TI Investment Analyst|
|TP0322 TI-Business Analyst-II|
|TP0326 TI-38 and TI-20|
But we placed these calculators in the "Scientific and Financial" section of the Museum...
Super slimline LCD for finance and business Ö with Constant memory* feature.
So lightweight and compact that you can take it anywhere. Features positive action keys designed to feel right to your fingers.
