I’ve recently acquired a collection of interesting classic PC related items. Among those items was a computer I have never heard about. It’s a Panasonic brand computer called JR-200U.
Built like a smaller (and more solid feeling) Commodre 64, this all-in-one unit has a built-in RF modulator to connect directly to a TV. It comes with 32K of RAM, which is unexpandable. Other ports it has are for a cassette interface, RGB monitor, RS-232, audio out, and Atari compatible joystick ports.
Along with the computer, I received eight different applications for it (on cassette), a demo program cassette, custom printer cable, custom RGB cable, cassette cable, aftermarket learning guide, and an official factory service manual.
As of this writing, I have not turned on the JR-200U. Although it has previously been used, many of the extras it came with are still in the original unopened condition. All of the software except the demo tape and one game is still shrinkwrapped. The RGB and printer cable are still stapled in their packaging. I would sure like to try those cables out, but the entire kit is in such pristine condition that the “collector” in me wants to leave it alone.
I’ll continue to research the item. Reading the service manual might reveal some hidden secrets about it. I will certainly post whatever information I discover in a future article.
