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.

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).
