The Panasonic FS-A1 is a MSX2 system. There are two versions: red or black case.
There is DESKPAC software built-in which starts automatically when the system is booted. It offers several interesting utilities : world time clock, chronometer, alarm, calculator, calendar and diary (see software section for screenshots). From here you can also choose to go directly to MSX Basic v2.0.
Concerning audio and music, the FS A1 is equiped with an AY-8910-3 chipset (or the YM2149 variant/clone) which is the very typical 3-voice square wave PSG with whitenoise. The computer is equiped with a pause button which hangs the system at will!
Some times later, the FS A1 MK2 (MaKe 2) will be released, offering some improvements (which ones?) like a numeric keypad above the cursor keys.
