Texas Instruments TI‑30 GALAXY


Brand: Texas Instruments
Model: TI-30 GALAXY
Type: Scientific calculator
Picture: TI-30 GALAXY
Batteries: A76 x 2
Lifetime: Introduced: 1984
Terminated: unknown
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 (this one)
  • TI-30 SOLAR
  • TI-30 S
  • TI-30 X
  • TI-30Xa
  • 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

Functionally quite close to the original TI-30 but for the addition of statistical functions. The layout of this calculator is quite distinct, and the keys are conveniently large.
