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