I bought recently a mk2. It works like a charm but there’s something is disturbing me. When I use it with a 8580(r5 if I remember well). The SID is not detected and I have the green led flashing but everything is working : I have sound. I have 2 8580 and both have the same problem. The only way I found to have the led stop flashing is to install a 6581 in the slot 1 and a 8580 in slot 2.
Anyone have an idea?
