Texas Instruments TI-99/4A

Texas Instruments · 1981

The TI-99/4 with a real keyboard, and the machine that fought Commodore in the 1983 price war — and lost so badly that TI left the home computer business after writing off hundreds of millions. Genuinely good sound and speech synthesis. Its failure is what let the C64 take the market outright.
