DATAMATH  CALCULATOR  MUSEUM

The first TI-30 manufactured in Italy for the European market used a different nameplate compared to the US original.

The first version of the TI-30 LCD used different electronics compared to the later model and the TI-30 II. You'll recognize the first version at the x!-key instead the n!-key. 

It took nearly four years since the introduction of the TI-25 and TI-35 slimline calculators before with the TI-30 II a calculator with the keyboard layout of the original TI-30 appeared. The picture shows the first, very rare variant.

This is the common version of the TI-30 II calculator. 

Together with the TI-30 LCD Texas Instruments introduced this scientific desktop calculator. 

The TI-30 LCD combined the electronics of the TI-30 II with a huge battery compartment to accomodate 2 A-cells. The calculator was sold only in some European countries.

With the TI-30 SLR Texas Instruments entered in 1982 the market of scientific LCD-calculators powered by solar cells. The calculator was developed by Toshiba. The result of this cooperation was a worse calculating precision but a perfect keyboard design.

The TI-30 III replaced the valuable slimline design of the TI-30 II using an identical calculator chip.

The TI-30 Galaxy was again a cooperation product between Texas Instruments and Toshiba. Compared to the TI-30 SLR the calculating accuracy was improved to 11 digits. Together with a smooth and logical arranged keyboard simply a perfect calculator. The Galaxy line brought us later wonderful calculators like the Galaxy 67.

The beautiful TI-30 Galaxy SLR added solar cells to the original TI-30 Galaxy introduced in the same year. In some countries the calculator was sold as TI-35 Galaxy Solar. 

The second edition of the TI-30 SLR uses a less power hungry calculator chip produced by Toshiba. This allowed both cheaper solar cells and the usage under less ambient light conditions.

The rare TI-30 SLR PLUS is identical with the late TI-30 SLR but shows its calculating possibilities.

This TI-30 introduced in 1986 is nearly identical to the earlier TI-30 III. With some small design variations the blue TI-30 survived till 1995 with a calculator chip introduced 1982!

The TI-30 STAT uses the electronics of the slimline TI-35 in the housing of the TI-30 III. One of the ways to create a TI-30 variant.

Just a small design variation.

With the production shift to Italy the TI-30 Galaxy got not only a black housing but a calculator chip developed by Texas Instruments. It is funny, but calculating accuracy was worse compared to Japanese design.

Just a small design variation

The TI-30 Solar added solar cells to the earlier TI-30 III. Everything else was identical.

The TI-30 SLR+ added some conversions and statistical calculations to the TI-30 Solar. It is identical to the TI-31 Solar and the TI-35 SLR.

Just small design variations to fit with the TI-30 STAT.

The time span before the introduction of the TI-30X family in 1993 was bridged with some design variants of existing products. The TI-30 Challenger got fresher colors compared to the blue and black housings of the earlier calculators.

This TI-30 STAT followed the yellow design of the first TI-30.

Just a small design variation of the TI-30 introduced three years earlier.

This TI-30 STAT changed back to the blue design of the first TI-30 STAT but got a 2nd-key instead the earlier INV-key for the alternative functions.

The time span before the introduction of the TI-30X family in the year 1993 was bridged with some design variants of existing products. The TI-30 Challenger got fresher colors compared to the blue and black housings of the earlier calculators.

Just a small design variation of the TI-30 introduced seven years earlier.

Starting from the very first TI-30 with a red LED-display in the year 1976 all TI-30 variants used an 8-digit display. This is for most calculations convenient but in scientific notation you'll get only 5 digits of mantissa. The TI-30X introduced a major improvement, the display capacity was eXpanded to a full 10 digit mantissa with two independent digits for the exponent.
Unfortunately the TI-30X introduced the Logarithm Bug not fixed until 2015.

The TI-30X Solar added very efficient solar cells to the 10+2 digit display capability of the TI-30X.

The TI-30Xa replaced the predecessor TI-30X within one year. The only enhancement was the added Constant-key.

The TI-30Xa Solar replaced the predecessor TI-30X Solar within one year. The only enhancement was the added Constant-key.

In the year 1995 Texas Instruments introduced a more robust version of the TI-30Xa Solar for school purposes.

The TI-30 S brought us the limited 8 digit display capability back to the TI-30 line. The electronics is identical to the TI-30 SLR introduced 12 years earlier! In most countries the calculator was sold as TI-25 X.

In 1996 Texas Instruments changes the design of the scientific calculators to a smoother shape. Everything else was identical the 1994 models.

Hong Kong Certificate of Education Examination (HKCEE) and Hong Kong Advanced Level Examination (HKALE) approved version of the TI-30Xa Solar.

The introduction of the two-line TI-30X IIS brought us two funny calculators. This TI-30Xa Second Edition and the TI-30 eco RS. The TI-30Xa SE is nothing else of a hybrid between the TI-30Xa Solar and the housing of the TI-32 Explorer Plus. It was only a short time available before it was discontinued December 2000. 

The introduction of the two-line TI-30X IIS brought us two funny calculators. This TI-30 eco RS and the TI-30Xa SE. The housing of the TI-30 eco RS is made of recycled plastics and together with the solar cells instead of batteries this allowed Texas Instruments Germany to use the "Umweltzeichen" sign.

In 1999 the TI-30 line of calculators received a great feature - a 2-line display. The upper entry line displays up to 11 characters and can be scrolled left and right up to 88 characters. The lower result line displays 10 digits of mantissa and 2 digits for the exponent.

The TI-30X IIS added solar cells to the otherwise identical TI-30X IIB.

The changes of the TI-30XA are minor, please notice the printing on the display screen.

Like the TI-30XA only some printing on the screen changed.

The changes in the design line are obvious, not only the color of the housing and keys changed, even the material of the display bezel is more valuable.

Like the TI-30X IIB this calculator looks more fashion now than before.

In the year 2007 the TI-30 line of calculators received a great feature - a dot matrix display with 31 * 96 addressable pixels allowing the calculator to display equations as they would be printed in a text book. In addition to this so called "MathPrint" mode the calculator sports a TI-30X IIB compatible "Classic" mode.
