TI-99/4

Released in 1979, the 99/4 was TI's first entry into the home computer market and many expected it to be a hit since it was developed by a major semiconductor company. However, due to many factors such as FCC rejection of the TI's RF Modulator and the failure of the cheaper TMS 9985 chip, the price was significantly higher then average family was ready to pay and the computer never gained much popularity. It was discontinued in about a year since the introduction to market. Approximately 25,000 units were sold. It was replaced by the improved TI-99/4A console in 1981 which ended up selling somewhere around 3 million units.
