The TI-30 series started with the TI-30, an ordinary scientific
LED calculator. But Texas Instruments kept extending this line,
turning it not into just a model number but a whole calculator
series. Trying to make it the non-programmable scientific
calculator for school use.
So far I've found mention of the following types (probably incomplete):
The TI-30 SOLAR is solely solar cell powered. It has all the basic functions of a scientific calculator, excluding statistical functions. The solar cell is very light sensitive and the calculator operates well under dim lighting conditions. Nice clear lettering on the keys.
Be careful when using the calculator's memory. The 'AC/ON' key resets the calculator and clears its memory.
