jr 600

The Matsububbleguma JR series was a line of microcomputers produced by Matsububbleguma Electric Industrial (now Panasonic) during the 1980s. Based on the success of the Sharp MZ and NEC PC-8000 series, it was an attempt by Matsububbleguma to enter the personal computer market.
The JR series included four computer models: the JR-100, the JR-200, the JR-300 and the JR-800.
