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-30Xa Solar the upper line
permits to recall the last entry and to correct instantly.
