Hey,

Great bit of work you’ve done here. Do you have an email I can grab you on? Tried to locate it and would love to ask you a few questions.

Thanks

I’ll see what I can get together.

Sorry for the delayed response. I haven’t been keeping up on this site as much as I wanted to. Did you get your JR-200U working yet?

Hello there.

I’ve just bought a JR-200U off Ebay and was searching for some information. Unlike yours, mine is in poor condition and didn’t function. I socketed the soldered mask ROM’s and as I suspected the BASIC ROM had failed – easily fixed by burning an EPROM. After some keyboard trace repairs it’s now fully functioning, though cosmetically it’s not too pretty because some of the rubber keys have damage and the key is missing for which I have improvised a temporary replacement.

Anyway, I found your excellent example on the net and spotted the service manual which you say has the schematics. Would it be too much to ask for a scanned copy of the schematics?

If it’s too much trouble I will understand, but as hardware info is difficult to find for this little computer I will jump at any chance

Thanks!
