I am finally finished this project. Just a couple of very minor things to do. I had a few teething problems on this one. A sticking right cannon solenoid(machinal issue), the right return lane eddy sensor took forever to adjust to get it to work consistantly. A couple of opto issues which are fun to chase down on this game. That combined with an intermittent loose wire on the trough opto board connector was doing my head in for a while. The machine goes nuts when an opto in the trough is not working, spitting out random balls during play. Adjusting the subway diverters was  another fun job. Everything seems sorted now though so time to play pinball!!!!
