Matsushita JR series

Matsushita JR series

The Matsushita JR series was a line of microcomputers produced by Matsushita Electric Industrial (now Panasonic) during the 1980s. The JR series included four computer models: the JR-100, the JR-200, the JR-300 and the JR-800. A version of the JR-200 called the Panasonic JR-200U was developed for the North American and European markets and was announced in January 1983.[1]

JR-300

The JR-300, released in 1984, was completely redesigned in comparison with the earlier JR-100 and JR-200 models. The JR-300 had a Zilog Z80A CPU as well as a second 6802-compatible MN1800A CPU to allow backwards compatibility with the JR-200.[2]
