The Tomy Tutor, originally sold in Japan as the Pyūta (ぴゅう太) and in the UK as the Grandstand Tutor, is a home computer produced by the Japanese toymaker Tomy. It is architecturally similar, but not identical, to the TI-99/4A, and uses a similar Texas Instruments TMS9900 16-bit CPU. The computer was launched in Japan in 1982, and in the UK and the United States in the next year.
