Awesome... all put together. Passed all tests well. Assembled and uploaded "Sammich_SID.hex" Boots up fine, but I can't navigate at all.. The only buttons that work (Menu,Shift,up, Down) all seem to bring up a "SID3 not available (CAn bus Errors" message I've check the orientation of the resistor arrays (Dots line up with dots on PCB) Any Ideas?
