The HX-32 is an improved version of the HX-31 as it comes with a Kanji ROM, stereo PSG sound and an optional RS-232C interface with switch.

Another switch at the back allows to choose mono or stereo for the PSG sound. The Kanji-ROM is the same as the one included in the HX-M200 cartridge.

This machine was released for the Japanese market with the "Pasopia IQ" label.

Although it's a MSX1 computer, it can use a part of the MSX memory to create a Memory Disk (feature generally reserved for MSX2 and higher computers).
