National JR 200

It is the successor of the JR 100.

The JR-200 had good features compared to its japanese competitors : 8 colors, 2400 bauds tape speed and 3 voices synthesizer.

But sadly there were no real graphic resolution, only a combination of semi-graphic characters.

The Panasonic JR-200U is the same computer but aimed at the american and european market. Read its page for more information, and a complete history text.

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.

It''s not really true that there weren''t graphics available. It''s pretty much on par with most other 8-bit computers of the time: the character set could be changed to create free-form images of full 256x192 resolution (with some limitations).
