♪♬♪♫ If it's the annoying little jingle you're looking for, ♬♫ ♪ ♫
I've recorded it here :

But the most interesting is certainly how?

I do not have Jacks To Open on the hand, but since we have many boards and bench tests, I could have programmed EPROMs, or even I could still use our TWISTER board (https://www.flipprojets.fr/AudioTwisterSound_EN.php).
And then connect an audio cable to digitize sounds on a PC, using MIC/Analog input.

But this is too much complicated !
I use a more simple and elegant solution, and everybody can do the same.

VPinMame, has implemented the emulation of this sound board quite fine, and there is an easy way to capture WAV sounds with this software. Of course, you must have VPinMame installed on your PC (and the ROM of the game you want to capture sounds).

Launch VPinMame and start the game.
Use the full interface (RESET the parameters, if you don't get the full display with lamp matrix/commands).

⤷ Press F4 to access the SOUND menu, and DEL to allow entering the sound command to play.
⤷ Press F5 to start recording.
⤷ Enter command 0E (that is the jingle/music sound) and press SPACE to launch it.
⤷ Press F5 to stop recording.

The result WAV file is now located in the "wave" sub-directory in the VPinMame directory. It's name is something like "Jack.....wav".
Then I use AUDACITY to remove the unwanted parts (silent at beginning, cut the too long sequence).

That all!
