Looks wonderful mate! Really developed a great appreciation for this machine getting the one you gave me up and running. While I did not replace all the optos, I did need to replace a few that were not working, and cleaned the rest and re-flowed the solder joints etc. It sure made a difference to the game - getting the optos right on STTNG is kind of like getting an old Gottlieb running - re-pin before looking to fix other issue, with ST do the optos first as a lot of issues are caused by them not working.
Cat wait to see some more pics, that playfield is awesome!
