Slingshots:
From the limited amount of photos of the bottom side of the playfield, and detailed photos of the topside there are no slingshots
and no mechanisms for them, did not appear to be any magna-coils present (What fliptronic used, instead of a solenoid operated arm).
Maybe they are missing but no way to tell, If someone has other photos, they would be much appreciated
Sounds:
Unless someone can find or present a living example of the sounds for JP to work with, it is all up to someone's imagination
Absent any kind of example or evidence, JP made the logical choice for a piece of 1968 electronics
As far as my part in this, all i did was take photos of the table, and make a rough mock up
then i tried to get info on the table, complete gameplay, a scrap of manual, video, anything, but no one could offer anything.
The most i got was very conflicting different sets of memories.
And it just sat on the PC, and i thought well that is kind of a waste because it would be kind of a neat looking table, even if someone did it totally to their own design
in lieu of any material to build it differently, so i showed it to JP because it seemed like the kind of thing he could have fun with recreating it to his own imagination.
So i really did not do anything but show him some vpx parts sitting on top of a playfield photo, and a zip file of photos.
At the end of the day, this is totally JP's work, and it is not a "Recreation" but a "What if JP Salas was the one making this in 1968" table.
Not enough concrete material is present to do a proper recreation, human memory is too flawed, as i have had several people tell me, in french, that they remembered playing this table when they were young adults, and how the multiball was very hard, which is impossible as the table has no multiball, it has no place for the multiple balls to exist at.
As well as totally conflicting memories of the rules, beyond the very short and incomplete text description
So....
