This computer was partially compatible with the Texas Instuments TI 99/4A. It had almost the same characteristics, except its main CPU (TMS 9995 instead of the TMS 9900 for the TI 99/4A).
The two languages (GBASIC and Tomy Basic) were only available in UK and US computers. The Japanese computers didn't have the Tomy Basic (a TI-like Basic), but a "nihongo basic" using japanese characters and words, e.g. "kake" meant "print", "moshi-naraba" meant "if-then".
This computer, known under the name Pyuuta in Japan had no really success outside Japan. It was followed by the Pyuuta Mark 2 and a game console called Pyuuta Jr one year later.

The Tomy Tutor was more popular in its home country of Japan than in the other two countries where it was sold:
The Tutor is not a clone of the Texas Instruments TI-99/4A computer from 1981, but they have much in common - perhaps a cooperative effort?
Very minimalist design - the case is mostly empty, with a little re-work on the motherboard.
Not much inside the typical Tomy game cart, either. Just a single ROM chip with the game burned into it.
