The TI-30 III replaced the TI-30 II within two years and defined the end of the Slimline series started in the year 1978 with the TI-50 LCD calculator. A similar calculator appeared in Europe with the TI-30

We recently discovered a TI-30-III manufactured in January 1985 by Compal Electronics, an Original Equipment Manufacturer (OEM) based in Taiwan, while this TI-30-III was produced in November 1984 by Inventec Corporation in Taiwan.

Within one year the keyboard design was slightly changed, view the later TI-30 III.

Later models used solar cells instead of the batteries, view the TI-30 Challenger.

The styling of the TI-30 III traces back to the BA-III prototype and was repeated with other models like the TI-35 II, BA-II and BA-35

If you are interested in the calculating accuracy of scientific calculators don't miss the Calculator forensics.

When production of the TI-30 III started in Italy a special version in a transparent housing was available. Don't miss the rare TI-30 III ClearCase.
