There are no known speech modules in existence for those few units with the connector. Most speech synthesizers were still shipped with the door that opened on the top, although very few had the connector inside. However, the success of software text-to-speech in the Terminal Emulator II cartridge cancelled that plan. The original intent was to release small cartridges that plugged directly into the synthesizer unit, which would increase the deviceвЂ™s built in vocabulary. The synthesizer used a variant of linear predictive coding and had a small in-built vocabulary. Speech synthesizers were offered free with the purchase of a number of cartridges and were used by many TI-written video games (notable titles offered with speech during this promotion were Alpiner and Parsec).

In the early 1980s, TI was known as a pioneer in speech synthesis, and a highly popular plug-in speech synthesizer module was available for the TI-99/4 and 4A. The TI-99/4A did ship with an RF Modulator. The TI-99/4 was sold with both the computer and a monitor (a modified 13вЂі Zenith Color TV) as Texas Instruments could not get their RF Modulator FCC approved in time.

The external power supply, which was different according to the country of sale, was merely a step-down transformer.ДЄvailable peripherals included a 5ВјвЂќ floppy disk drive and controller, an RS-232 card comprising two serial ports and one parallel port, a P-code card for Pascal support, a thermal printer, an acoustic coupler, a tape drive using standard audio cassettes as media, and a 32 KB memory expansion card. This area gets very hot so users commonly refer to it as the вЂњcoffee cup warmerвЂќ. The power regulator board is housed below and in front of the cartridge slot under the sloped area to the right of the keyboard. The TI-99/4AвЂ™s CPU, motherboard, and ROM cartridge (вЂњSolid State SoftwareвЂќ) slot were built into a single console, along with the keyboard. Its predecessor, the TI-99/4, featured a calculator-style chiclet keyboard and a character set that lacked lowercase text.

The TI-99/4A added an additional graphics mode, вЂњlowercaseвЂќ characters consisting of small capitals, and a full travel keyboard. 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 Texas Instruments TI-99/4A was an early home computer, released in June 1981, originally at a price of US$525.
