- The Tomy Pyuuta, released in Japan in 1982, was the direct ancestor of the Tutor, featuring rubber chiclet keys, G-BASIC with sprite support, and built-in paint box.
- Tomy targeted kids and teens with the Pyuuta, marketing it as a fun computer, and it became reasonably successful in pre-MSX Japan.
- The Pyuuta's design was finalized by spring 1982, manufactured by Matsushita, and it used the TMS 9995 CPU and TMS 9918A VDP from Texas Instruments.
- Tomy exported the Pyuuta to the UK as the Grandstand Tutor with Tomy BASIC (based on TI Extended BASIC) and to the US as the Tomy Tutor, but both variants lacked bundled joy controllers and cassette cables.
- Marketing documents for the US market, found in a storage unit, refer to the computer as 'TomyOne' or 'Tomy-1' and describe a model with included controllers and cassette cable, matching the Pyuuta rather than the actual Tutor.
- The documents propose direct competition with the TI-99/4A, Atari 400, Commodore VIC-20, and Timex Sinclair 1000, highlighting the Pyuuta’s graphics and ease of use.
- The American Tomy Tutor failed commercially due to intense competition, leading Tomy to exit the US home computer market by 1984, though Japanese support continued until 1985.
