TI-30
From Free net encyclopedia
Image:TI-30X IIS.jpg The TI-30 is a scientific calculator introduced in 1977 and manufactured by Texas Instruments. The TI-30 series calculators on sale today are direct descendants of the original TI-30. The original TI-30 was notable for its extremely low cost, around $25. This was far less than the retail prices of other scientific calculators of the era. For example HP's cheapest scientific was still well over US$100. The low-priced TI-30 made scientific calculators far more available than before, for example to the common high-school student. The TI-30 may be the best-selling calculator ever, with an expected 15,000,000 manufactured during its lifespan from 1976-1983.
It is rumored that the original TI-30 got its name from the retail price of US$29.95 or US$30. This seems unlikely, however, as the original MSRP was $24.95.
The modern TI-30 series consists of capable, low-priced scientific calculators, which are evolutionarily related to the original TI-30.
