Soldered the flashed ROM to another 233X card I had and success! Glorious MIDI music emitting from my speakers. Very good work. I will give it a try and exchange the ES981P with ES982 written to a MX29F1610 Chip. I do have the same 233X card. Hope I will be able to make it work. Anyhow the card has …

I get sound, even though there are still a lot of issues. Of course you also have to push the virtual power button of the …

I received my 2 ARGUS cards a week ago and finally found time during the weekend to solder everything. What can I say: both cards are working, even though my soldering skills are not good at all. I am really happy! Thanks a lot to shock!

But for the "original replica" what should be done? 1) Component placement and routing: a) should be left as close to original as possible (even if it degrades output quality and looks bad); b) can be re-done in some places to get some improvements; c) should be fully made from scratch (as an …

As I have a CT1900 I can help you to replace The U7 ROM. By the way, I helped to repair a different soundcard …
