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. 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 RAM-Disk or Memory Disk (feature generally reserved for MSX2 and higher computers).
