This is a classic MSX 1 computer, quite similar to the HX-10, except that the shape is different and there are two cartridge slots.

Its special feature seems to be a primitive word processor software built-in ROM. You need a separate Kanji ROM cartridge for it to work.

Does someone know the other differences?

In its native country (Japan), the HX-20 was also named Pasopia IQ to fit in the Pasopia family developped by Toshiba. Pasopia IQ was used for their MSX computers serie.

There was also a HX-21 computer. It had some minor design changes: like red line - instead of green - below brand and model names. But the main difference seems to be a RGB video output for the HX-21.

We need more info about this computer ! If you designed, used, or have more info about this system, please send us pictures or anything you might find useful.
