This mod is required or you stand to damage the data bus on either SID at some point in future - only if both SIDs are using the same chip select and base address (dual mono, psuedo stereo). Special thanks to Dave Curran for helping simplify this fix. On a standard SID2SID board it's not configured in such a way there will be a problem. #commodore #c64 #dualsid #sid #diy
