 When TI introduced the TI-99, Tramiel turned the tables on them by pricing his machines below theirs.A price war ensued, causing a dramatic decline in home computer prices, reducing them as much as eight times over a period of a few months.In May 1981, the Atari 800's price was $1,050, but by mid-1983 it was $165 and the 400 was under $150.
