Driver board lamp connectors A3J2 and A3J3
Lamp, relay and lamp-driven coil outputs leave the driver board on A3J2 (10 pins) and the double-sided A3J3 (pins 1-25 on the component side, letters A to /C on the solder side), with each transistor fed from a 74175 latch (Z1 to Z12). Fixed pins, the same on both games: A3J2-6 lamp ground; A3J3-1 and A3J3-A ground, A3J3-B +5 V; lamp grounds on A3J3-17, C, S, U and Z; index keys at A3J3-8 and A3J3-J; A3J3-L unused. A3J3-/A is the game over relay Q (Q1), /B the tilt relay T (Q2) and /C the shoot again lamp (Q4). On both games sound 16 leaves on A3J2-9 from Q10, and the general illumination relay drive is on A3J3-14 (Q18). On Haunted House the lamp-driven coils are A3J3-13 trap door (Q17), 23 right side kicker (Q16), 24 cellar five-bank reset (Q14) and 25 K relay for the up-kicker (Q13); on Black Hole A3J2-10 ball return gate (Q9), A3J3-22 ball lift kicker (Q15), 23 shooter lane ball release (Q16), 24 upper hole kicker (Q14) and 25 lower hole kicker (Q13).
