Description

This FM Stereo PAK is a clone of the Panasoft FM-PAC, but without the SRAM function, manufactured by the club Gouda in the Netherlands.

This cartridge contains the MSX-MUSIC chip with

its specific BIOS
extended BASIC instructions - see MSX-MUSIC BASIC
a 3.5mm stereo audio out connector. One channel contains the FM drums eventually mixed with the PSG sound, the other the FM melody channels.

The cartridge also has a built-in software, which can be started by running CALL FMPAK or _FMPAK from BASIC. Here you can listen to various demo sounds. Contrary to the original Panasoft firmware, which can be runned on MSX1, the Checkmark firmware requires a MSX2 or higher computer.

The FM Stereo PAK was also produced by several other people, sometime with more or less modifications like the PCB or/and sound output quality.
