Picked up yesterday a Blackwater 100. Could not test a play; it was giving the "ball missing" error.
Came back home, tried and it worked.
Tried again this morning; "ball missing".
I reflowed all the soldering for the opto through boards, still having the same issue.
If it is realted to the optos as I fear; where can I find optos for a 6803? They seem quite specific.
Many thanks in advance!
