Hardware

The Panasonic FS-SR021 is a set composed of a cartridge and a disk, released in 1988 by Panasonic.

The cartridge contains

a ROM with MSX2 Word Processor (MSX2用ワープロカートリッジ) - it's actually the same Japanese Word Processor with MSX-JE support as the firmware of the MSX2+ FS-A1WX computer, but slightly adapted
Kanji-ROM level 1 & 2 to provide Kanji support
16kB SRAM

The mapper of the ROM with the Word Processor is similar to the mapper of the FS-A1WX firmware, but with some differences that need to be investigated:

which keys replace the "取消" (Cancel) and "実行" (Execute) keys as the MSX2 computers don't have these keys?
how potential conflicts with Kanji-ROM present in used MSX2 machine are prevented?
how does work the software switch, that replaces the front switch on the FS-A1WX?

Help needed

While the ROM is dumped, help is needed from someone who has the cartridge to reverse engineer the mapper and other details to allow it to be emulated. If you can help, see this thread.

Firmware

The firmware is not launched automatically when you boot the machine, except when you have used this option with the software switch. So, you need to use CALL MENU or _MENU the first time you want access the firmware.

By comparison with the version available on the FS-A1WX, it's almost the same version of Cockpit software, the main difference is the additional software switch.

The firmware menu includes 10 options:
