Panasonic FS-PW1

The Panasonic FS-PW1 is a set consisting of:

  • Japanese word processor cartridge with MSX-JE and Kanji-ROM Level 1 (JIS1)
  • monochrome 24-dot matrix thermal transfer printer that directly attaches to the cartridge with a ribbon cable
  • Panasonic FS-AA181 AC Adaptor to power the printer

The built-in firmware is exactly the same as in the National FS-4600F.

The advantage of connecting the printer to the cartridge was that the printer did not need its own Kanji ROM. The disadvantage was that the printer only works with the integrated word processor software.

Note: It is however possible to create a cable to attach the printer to the regular MSX Printer port, in which case the control cable is also no longer necessary and the printer can be used with other software. (details?)

The cartridge has SRAM that is backed up by two removable AAA batteries.

There are two switches. The one on the left of the cartridge can be used to disable the integrated word processor, while the one on the right can be used to disable the integrated Kanji-ROM.

A special control cable is also needed, without it the printer will not work. It connects on the left side of the cartridge to what looks like a 3.5mm headphone connector, and needs to connect on the other side to the MSX printer port.
