So have started to rebuild it and going fairly well. Having stripped the coin mech, it's running on 6d.
I have a real problem with the first set of switches behind the 'Start' button. In short they are not aligned properly at all so it won't light the button and I can only start it manually. I am sure I can sort this.
Biggest problem is the right hand relay in this photo. What does it do? I have got all of the others freed, but this one.... just doesn't seem to activate.
