Texas Instruments TI-30XB


Brand: Texas Instruments
Model: TI-30XB MultiView
Type: Scientific calculator
Picture: TI-30XB
Batteries: CR2032 x 1
Lifetime: Introduced: 2005
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):

The TI-30XB MultiView and its variant, the TI-30XS which has a different colour scheme and a solar cell, introduced in 2005 is still for sale as I write this in 2024.

According to this Wikipedia page (link valid 2024-06-13), the TI-30XB and the TI-30XS where Texas Instruments’ very first non-graphing TI calculators with a dot-matrix display.

It is called MultiView because it can display results in two modes called Classic and Mathprint. In Classic mode, results are shown as decimal results. Using Mathprint, results are shown mathematically. For example, in RAD modus the result of "cos(π/4" will show the mathematically correct answer: "√2/2".

The "F◄►D"-key (and other fraction keys) can be used to turn decimals into fractions and vice versa. For instance, type the number ".125" followed by the "F◄►D"-key and the equivalent fraction "1/8" is shown.

Some functions are available under menus. It has statistical functions, it can work with tables showing a list of values of a given formula and a specified step size.

Operations can be replayed. When I found this specimen on a flea market I could scroll all the way back to see what the previous owner had calculated previously.

It has multiple memory locations called "x, y, z, t, a, and b".

All in all a powerful scientific calculator for school use.
