MATSUSHITA
National JR 100

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.

I have one!! it was my first computer, it was BASIC based, I learned how to program with this baby even some sort of machine code (via USR function). I still have it, was working when stored. Great memories!!

There is a JR-100 emulator available, appears to be Japanese only. See http://www.asamomiji.jp/kemusiro/index.php?JR-100$A5$A8$A5$DF$A5$E5$A5$EC$A1$BC$A5$BF (use Google Translate to view in English)
