Texas Instruments TI-30 STAT
Brief History
Successor of the japanese-american cooperation-made TI-30 III, production of a variation named TI 30 was started in Italy in 1985. In addition to basic model, a variation with statisctical calculation ability were developed as TI 30 STAT, and was sold for a bit more expensive than TI 30.
