Nothing is known about the history of this computer which was probably sold only in Japan.

It was one of the rare professional computer to use the 16-bit Texas Instruments TMS-9900 microprocessor, also used in the [TI-99/4](/museum/texas-instruments-ti-99-4a/) home computer.

A Basic interpreter and Assembler were available on diskette.
