dystility Posted June 8, 2016 Report Share Posted June 8, 2016 Hi there, I'm building a midibox SID with 1 core and 2 8580s and I'm having a problem. My SID isn't working properly - but weirdly, the test-tone application works, and even weirder, the interconnection test does NOT work. When I simply boot up the core and 1 SID (I've tried switching them, the same problem with both boards) and play some midi notes (tried both a keyboard and MIOS), I get no sound. Yet the test-tone works fine. I have tested the conductivity and as far as I can tell both boards are connected fine. One thing I was confused about, is the lack of an MD port on the SID, when there is a space for it on J10 of the core, also having no connection between the SC port as illustrated in the connection diagrams. Are these anything to be worried about? Also with the interconnection test, no matter what I play, all the pins that the test should change are held at 0.27V which is also pretty strange. I know the SID works because I got it making sound a couple of years ago, it just had no control surface then, and I can't remember how I connected it then, so its possible I did connect something differently. I brought it out again now to finish it and have run into this problem. I have tested all the core and SID voltages and both are fine. Any suggestions would be greatly appreciated, thanks!
