After Microsoft left the [MSX project](/museum/msx-1/) in 1986, ASCII continued alone. They presented a new improvement of the [MSX 2](/museum/msx-2/) standard in 1988.

No great enhancements, the MSX 2+ has 19268 colors instead of 512, some more graphic / KANJI resolutions and the built in MSX-Music, providing 9 channels of FM sound without drums or 6 channels FM sound with 5 FM drums.

The Panasonic **FS A1 WX** features the Rensha Turbo, which is a built-in auto-fire system. The repetition speed can be adjusted with a slider. Its ROM contains A1 Cockpit Internal Software, MSX Word Processor, MSX-JE, FM-BIOS (MSX Music Basic ROM) and JIS 1st+2nd Class Kanji Support (256KB).

The Panasonic **FS A1 WSX** is the successor of the FS A1 WX from which it differs very slightly: no tape support anymore, S-Video interface added and color print support with Word Processor (and color printer).

Contrary to Sony and Sanyo MSX2+ systems which used a Z80A, the Panasonic systems used a Z80B cpu which could be set up to 6 MHz.
