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. Compared with the traditional TI-34 the upper line permits to recall the last entry and to correct instantly.

In 2004 Texas Instruments introduced a new design line with a really prominent name plate and some modern applications like an aluminium bezel around the display. Please start your journey with the new TI-30X IIS.

Stokes Publishing Company, Inc. based in Sunnyvale, California sold a companion for the teacher, view the wonderful TI-34 II Overhead Calculator.

Please remember the Canon Palmtronic MD-8 sporting a two-line display already in 1979.
