Panasonic FS-A1WX

The FS-A1WX was an MSX2+ computer with enhanced V9958 graphics, MSX-MUSIC sound, built-in floppy storage and Japanese word-processing firmware.

It combined the mature MSX2+ platform with practical home-office software and Panasonic’s adjustable CPU turbo mode.

Historical Significance

• It combined the mature MSX2+ platform with practical home-office software and Panasonic’s adjustable CPU turbo mode.

Collector’s Notes

• Drive belts, keyboard switches and Japanese firmware disks should be preserved; internal RAM upgrades are common.
• Memory, storage, displays and expansion hardware should be documented because configurations often changed during a system’s working life.
