I'm not completely following, but the SwinSID shows up with Control Port Fail, no pot x/y support for the control ports.
Correct. SwinSID has no paddle support and showing BAD on Control Port and 6581 Test is correct. Thats not the "Problem"
Problem i have here is that only with SwinSID plugged in instead of real SID or SwinSID Ultimate or no SID there are disturbances/crossbeams on the screen.
Still waiting for TurboMicha to test a SwinSID in his KU-Board and telling us the Result, so that we know if its a local Problem with me or a general Problem with the SwinSID in Replica Board
