Hi 72GTO
what exactly means (post-1) "Rollovers initially score" ?
I fully agree with fredsmythson 's post-2. You have plenty of stuff on the playfield with text "50 or '500 and add bonus' " - the most simple feature is the "50" - an un-lit place should give 50 points.

To give 50 points: The "D-50-Points-Relay" is made pulling - it establishes Self-Hold-Current (stays pulling for a while) - it calls for help of the motor (motor will turn 120 degrees - a third of an revolution) --- the turning motor pulses five times the "N-10-Point-Relay" --- the motor ends the turn of 120 degrees and the D-Relay quits pulling --- end of feature.

Have a game started - go to the D-Relay - gently press the armature of D-Relay - look at the D-Relay (does it stay pulling ?) and listen to the motor (does it turns and then stops ?) - then look at the Score-Drums (have 50 points been added ?) --- Write about this test, greetings Rolf

Hi 72GTO
I pick the "making points when a drop-target drops". Post-4, JPG, The "B" is lit and the "D" is lit and the "E" is lit. All the other lamps in that area are unlit. Making the "7" target to drop must give 50 points (no bonus given) - the same (just 50 points) is on "8,9,10".
The "6" is "single lit - the "E" lamp is lit - making the "6" target to drop must give 500 points AND one bonus is added to the bonus-ladder.
The "2,3,4,5" are "single lit - the big "B" lamp is lit - making an "2 or 3 or 4 or 5": You must get 500 points AND one bonus is added to the bonus-ladder.
The "1" is "double lit - the "B" AND the "D" lamps are lit - making the "1" target to drop must give 5000 (!) points AND TWO bonus are added to the bonus-ladder.

When the ball rolls over the "A" Rollover-Button (You get 100 points and) the "B-Light" turns-off and the "C-Light lights-up". Also (near "D") the lamp to "1" turns-off and the lamp to "2" lights-up. Also (near "E") the lamp to "6" turns-off and the lamp to "7" lights-up.
When the ball then rolls over the "A" again: (You get 100 points and) the "C-Light" turns-off and the "B-Light lights-up". Also (near "D") the lamp to "2" turns-off and the lamp to "3" lights-up. Also (near "E") the lamp to "7" turns-off and the lamp to "8" lights-up.

So a player may say: Every time the ball rolls over the "A" Rollover-Button: The big lights "B and C" alternate, the little lamps on the "D and E side" make a step forward, clockwise (((always is lit either "1-6" or "2-7" or "3-8" or 4-9" or "5-10"))).
So when we play - the goal is: To make the DOUBLE lit target to drop - getting 5000 (!) points and the bonus-ladder is stepped-up TWO times.

As the "A" Rollover-Button makes this stepping on the Target-Lights - hitting a bumper "Q, R": ALSO make this stepping on the Target-Lights.
Not only the "B" and "C" alternate when "A, Q, R" are actuated - ALSO alternate on "G,H", "I,J", "K,L", "M,N" - they alternate / switch between "only 50 points - 500 points and one bonus".
The "O" and the "P" do not alternate - both always give 500 points and one bonus.

All this "action on the lights" is made because the "I-Advance-Unit-Relay (Mini-Stepper)" is made to step - and again to made to step and again and again.

72GTO - want to take my description here - and look-up in Your pin - and write "what is functioning, what is not functioning", greetings Rolf
