Hi Kaps
in Your post-1 I read "credits are at zero" --- here https://www.ipdb.org/showpic.pl?id=1683&picno=27671&zoom=1 we see in the lower left corner the Credit Unit. Have the main power cord unplugged (Safety Reasons) - see TWO Coils are mounted on the Unit - one for to add Credits (step up the Unit) - can You manually step up one or more steps ? Doing so see how a rod mounted on the "wheel with tooths, gear" does actuate - CLOSE (?) This switch is to be manipulated ( a blade heavily bent or using a Jumper-Wire on the Solder-Lugs on the Switch) ALWAYS CLOSED - and You have set the pin for "free play" - simply press the Start-Button (Front of the Pin) to start a Game. Greetings Rolf
