Notes:	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): TI-30 TI-30 LCD TI-30 II TI-30 III TI-30 SLR TI-30 D TI-30 SCIENTIFIC TI-30 SLR TI-30 SLR+ TI-30 STAT TI-30 Challenger (Solar) TI-30 GALAXY TI-30 GALAXY SLR TI-30 SOLAR TI-30 S TI-30X (this one) TI-30X Pro TI-30Xa TI-30Xa/SE TI-30X Solar TI-30Xa Solar TI-30XB TI-30XS TI-30XII TI-30XIIB TI-30XIIS TI-30 ECO RS TI-30 SR 50 The TI-30X is a 10 digit scientific calculator for school use with very nice big soft keys and clearly readable markings. It has the standard set of scientific functions, statistical functions, and fractions. The fraction of a decimal can be determined by using the "F◄►D"-key. This doesn’t work for all decimals. For example, when typing ".333333333" followed by the "F◄►D"-key nothing happens. However, pressing it after first dividing "1" by "3" the fraction "1/3" is shown. Its display is very readable and clear. Errors are indicated by displaying the message "Error". Many thanks to Richard Pilkington of the University of Salford for donating this calculator to the museum.
