This mini forum is intended to provide a simple means of discussion about the Panasonic JR-200U computer. If you want to share your own experience or memories, or add relevant information about this system: post a message!

The Service Manual is now available at Vintage Volts. All in all, a lot more has been discovered about the machine. My current guess is that the CPU runs at 1.366 MHz.

Hello, I want to let enthusiasts know that there is currently a mint Panasonic JR-200U listed on eBay by user ID seattlegoodwill. They are very reputable and seem to always have a good stock of "old computers." Save it from the landfill! Lance

I''ve been trying to hack the JR-200UP for some time now and have discovered a thing or two (the technical manual WOULD have been a nice addition...) See the findings here: http://www.kameli.net/marq/?page_id$1270

This message is for J. Mitch Hopper - I recently bought a Panasonic JR-200 but with no manuals. Cute little computer, but I am going to need manuals to figure anything out.
I see from the postings that you have docs - could you please email them to me at robert.saler@gmail.com.
Cant do anything without them - sorry for the trouble.
Thanks - Robert

I have a JR-200U and need any information I can find, could you please email me the manual to clockmeister@internode.on.net J. Mitch Hopper?

Thanks in advance.

Note to athansoft:
Alas, I forgot to send you the manual. Very sorry for the delay. Just sent it.

My email is athansoft@hotmail.com. Thank you J. Mitch Hopper. I am waiting for your pdf files

I have manuals. If you want them, post a message here with contact info. I will email the PDF on request.

I have a Panasonic JR-200UP but without manuals. Could anyone sent me photocopies or pdf file of it and I''ll pay him. Thank you

I have a JR-200 new-in-the-box with manuals. Looking over the detailed memory map,I see that it is exactly the same as the Radio Shack CoCo - right down to the free, unassigned space.

Emulator resides on

I'd need the technical or development docs to make the emulator better.

I still have an old Panasonic JR-200U that I bought from J&R Music World in
NY in 1984 or so. For the day, it was actually a pretty nice little machine.
32KB, better graphics than the CoCo, but still not very good, a Motorola
6802 processor, fairly decent sound, an independent timer (which is how it
ended up as a fancy alarm clock for me for a couple of years). I didn't get any peripherals with it, but I did have the cassette cable and used a crappy little Radio Shack cassette recorder to save/load my programs. I had no software except for the stuff I wrote myself, but it was still a great first computer. I never really figured out how the MON debug monitor thingy worked.
Also, I never got a real owners manual. When J&R shipped it to me, it was missing the manual all together. After several phone calls, they agreed to send one. What I got was a Xerox copy of the manual. That kinda sucked, but
it worked.
