The Texas Instruments TI-99/4A was an early home computer, released in June 1981, originally at a price of US$525. It was an enhanced version of the less successful TI-99/4 model, which was released in late 1979 at a price of $1,150. The TI-99/4A added an additional graphics mode, "lowercase" characters consisting of small capitals, and a full travel keyboard. Its predecessor, the TI-99/4, featured a calculator-style chiclet keyboard and a character set that lacked lowercase text.

Famous quotes containing the words texas and/or instruments:

    The pleasure of jogging and running is rather like that of wearing a fur coat in Texas in August: the true joy comes in being able to take the damn thing off.
    Joseph Epstein (b. 1937)

    Water, earth, air, fire, and the other parts of this structure of mine are no more instruments of your life than instruments of your death. Why do you fear your last day? It contributes no more to your death than each of the others. The last step does not cause the fatigue, but reveals it. All days travel toward death, the last one reaches it.
    Michel de Montaigne (1533–1592)
