The National (also known as Panasonic or Matsushita in other countries) JR series was pretty popular in Japan. Small quantities were sold outside Japan, in New Zeland among other countries.

Little is known about the first system of the range (please help!). It was obviously an initiation machine with black & white display and rubber keyboard.

The JR 100 was followed by the JR 200.

Thanks to Murray Moffatt from New Zeland for most of the information and pictures.

We need more info about this computer ! If you designed, used, or have more info about this system, please send us pictures or anything you might find useful.
