Description

Computer

This machine was aimed at the Japanese market - see HX-22 series for the technical details

As for many machines with the "Pasopia IQ" label, the PSG sound output is stereo, with a switch at the back. 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 computers with version 2.1 of MSX-BASIC).

Official price: ¥89,800

This machine has been localised for two countries:

Firmware

The built-in firmware is the Japanese Word Processor, that is also available on the other Japanese computers of the HX-2x serie. It's the same version as on the HX-S501 cartridge.

From BASIC, the firmware can be launched with CALL JWP or _JWP. It includes the additional BASIC commands for Memory Disk, RS-232C and printer.

However, you need to have the HX-M200 Kanji ROM Level 1 in one of the cartridge slots. Note that the corresponding machine in the blueMSX emulator includes this cartridge.

It is possible to use other Kanji Roms, but if you use the Sony HBI-K16 Kanji ROM Level 1, CALL JWP leads to a I/O device error. To bypass this problem, an addendum to the manual of the Sony cartridge gives the solution:

10 FOR I = &H9080 TO &H9120 : POKE I, &HC9 : NEXT I
20 CALL JWPKAKU
