An RF modulator allows the use of a television as a monitor. Lowercase letters are displayed as small caps, rather than separate glyphs. TI BASIC, an ANSI-compliant BASIC interpreter based on Dartmouth BASIC, is built in and includes support for graphics, sound, and file system access.
Speech synthesizer
A plug-in speech synthesizer module was available for the TI-99/ 4A. Used by video games such as Alpiner and Parsec. Alpiner's speech includes male and female voices and can be sarcastic when the player makes a bad move.
