TI-99/4A

The Texas Instruments TI-99/4A is a home computer manufactured between 1981 and 1983. The interesting aspect of the TI99/4A retro computer is the CPU: it already works at 16 bit. The standard home computers produced at that time, such as the Commodore 64, the Commodore 128, the C16, work at 8 bits.
