The TI-99/4 series consisted of two computers by Texas Instruments.
They used the TMS9900 CPU, clocked at 3 MHz, and were the first 16-bit computers released for the home market.
TI-99/4
The TI-99/4 was released in late 1979.
TI-99/4A
The TI-99/4A was released in June 1981. It was backward compatible with TI-99/4 titles. However, due to the improved graphics capabilities of the TMS9918A, not all TI-99/4A titles could be used on the TI-99/4.
Development
In 1977, two teams at Texas Instruments were working on two separate projects, a computer, and a video game console. The two projects were merged into the TI-99/4 series.
