Matsushita JR series
The National JR series (including some models also sold as the Panasonic JR) was a line of 8-bit personal computers developed by Matsushita Communication Industrial Co., Ltd., a division of Matsushita Electric Industrial (now Panasonic). Based on the success of the Sharp MZ and NEC PC-8000 series, these computers aimed primarily at the home computer and educational markets during the early 1980s.
The JR series included four computer models: the JR-100, the JR-200, the JR-300 and the JR-800. All four were sold under Matsushita's 'National' brand; the JR-100 and JR-200U were also sold elsewhere as 'Panasonic' (another Matsushita brand).
The JR series found a strong foothold in Japanese schools, particularly the JR-200, which became a standard machine for teaching programming in BASIC.
