Oh yes, this project. One reason for trying to assemble a 520st, as I need a working ST to test it myself ....

Hi!

Thanks to great generosity of DarkLord, I have the original JRI4096C board on my desk for analysis and RE. It's a fairly simple circuit, so I should soon publish a reconstructed schematic and a working clone assembled from it. Let me just get back from vacation

Of course, I'll let you know when I'm done...

Cheers

Hi,

Diagram has been restored. I designed new PCB for clone and sent to manufacturer.
After positive tests the documentation will be published on my www.
