where are all the leds that r****n dog put on their boards near the test points that really serve no purpose? 
Where are all the custom SMD I.C.s that you cant buy that p**led put on their boards? 
Why are all the traces so thick? 
Why do you have Machined I.C. sockets fitted to the main I.C.s ? do you expect us to replace components instead of buying a whole new board if something in our machine causes one of these components to fail? 

 

Well done Mike. I have repaired an after market pinball board  made by every modern company except for home pin  i really can't understand why?
