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 SLR1986?
  • TI-30 SLR+
  • TI-30 STAT
  • TI-30 Challenger (Solar)
  • TI-30 GALAXY
  • TI-30 SOLAR
  • TI-30 S
  • TI-30 X
  • TI-30Xa (this one)
  • TI-30 Xa/SE
  • TI-30 X Solar
  • TI-30 Xa Solar
  • TI-30 X II
  • TI-30 X IIB
  • TI-30 X IIS
  • TI-30 ECO RS
  • TI-30 SR 50

The TI-30 S is solar cell powered, and quite small. It has all the basic functions of a scientific calculator, including statistical functions and fractions. There are three different memories to store numbers. The keyboard has very nice and easy to use keys.
