The HX-10 is the most known computer released by Toshiba. It exists in various versions, some of them have only 16kB RAM, but Toshiba was the first to offer an MSX computer with 64kB RAM.

All models have only one cartridge slot. However, there is an expansion bus on the back of the computer to attach the Toshiba HX-E600 slotexpander, which provides a second slot and an extra I/O slot.

The colorful keyboard, with blue cursor keys, a red STOP key and a green GRAPH key lightens up the computer.

Initially aimed at the Japanese market under the label 'Pasopia IQ', this machine has been localised for several European countries. All the international versions have 64kB RAM.

This computer was sold with a demo tape (except when it was part of the HX-10 Kit sold only in Great-Britain).

All these versions have a Japanese QWERTY keyboard.

European versions

Unlike in Japan, in Europe, Toshiba generally marketed them as the HX-10 without the extra letters at the end. The designation on the top will simply say HX-10, but the label at the bottom will typically show the full designation. Additionally in most cases the box will also show the full designation. The exception is the HX-10P, which will say both HX-10 on the bottom label and on the box.

Product Region Keyboard Video and audio out
HX-10AA BE, NL QWERTY with £ key RF, composite video and audio
HX-10E ES QWERTY with accent key RF, composite video and audio
HX-10F FR QWERTY with accent key RGB
HX-10P aka HX-10 DE, UK, IT QWERTY with £ key RF, composite video and audio
HX-10SF FI QWERTY with accent key RF, composite video and audio

Strangely enough Toshiba did not offer localised keyboard versions in Europe, using just two keyboard variations. Either an 'International' QWERTY keyboard with a £ key, or an 'International' QWERTY keyboard with an accents key. The picture shown on the box is the same for all models, and depicts the model with £ key.
