    Anyone know if the beeps and boops of Gottlieb system 1 are contained on the sound board, say in a chip? Wondering if I could wire a harness to trigger 3 different sounds from a different source.

    Not sure about that. What I do know is, all Gottlieb System Ones with the sound board are downward compatible if you want to install a chime box.

    Hello,
    Yes, you can very well control the "bip-blup-555" Gottlieb board from a different source.

    This card is very basic, it has three circuit-based oscillators 555, each triggered by the grounding of a pin.
    The three frequencies generated (594 Hz, 266 Hz and 153 Hz) are then mixed and amplified by a LM380.

    It require a 24 v DC power on pins 9 and 6/7 (GND).

    The tones are activated by grounding one (or more) pin : 1, 2 or 3
    - Connected to ground = tone
    - Not connected = no tone

    The board has been designed to replace directly the xylophone coil controls (similar, activated by grounding).

    Thank you for the thorough response! I am going to play around with some other sounds for Count-down. It's sitting next to Dragon and if both machines are being played at the same time the sound can be a little maddening.
