The Panasonic FS-A1WSX was the last MSX 2+ made by Panasonic. It was the sucessor of FS-A1WX and incorporated few changes like S-Video output, no tape support, color printer support and a improved A1 Internal Cockpit software with a Kanji color word processor.

Contrary to other MSX2+ systems the Panasonic FS-A1 used a Z80B processor which could switched via software to 6Mhz. This model supports up to 256KiB of RAM with a little soldering need. 512 KiB is also possible with a more complicated modification.
