The Panasonic FS-A1WSX released in 1989 was the last MSX2+ made by Panasonic. It was the successor of FS-A1WX and incorporated few changes like S-Video output, no tape support, color printer support and an improved A1 Internal Cockpit software with a Kanji color word processor.
Contrary to other MSX2+ systems the Panasonic FS-A1 used a Z-80 compatible MSX-Engine (T9769x) which could be switched via software to 6 MHz. This model supported up to 256 KB of RAM after doing a little soldering. 512 KB was also possible with a more complicated modification.
