The vapourware Tomy expansions:
\- The 5"1/4 diskdrive\
\- The printer\
\- The big box under the tutor might be the the RAM expansion (+48k)\
\- The little black box before the diskdrive might be the speech synthesizer...
These devices seem to have never been released...

This computer was partially compatible with the [Texas Instuments TI 99/4A](/museum/texas-instruments-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](/museum/tomy-tutor-mk-ii/) and a game console called Pyuuta Jr one year later.
