Merci à tous, j'avais ouvert plein de liens google et jamais trouvé les coordonnées de la puce à retirer
Dites j'ai retrouvé l'annonce sur ebay, ils parlent de bypasser une diode D23, vous en pensez quoi ?

Data East Pinball Machines can use this RAMTRON part to replace the 6264 RAM at location 5D, but will need diode D23 bypassed to ensure proper voltage to the RAM. May also work with other pinball machines where the current RAM is a 6264 IC, however similarly a diode in the battery/memory circuit will need to be bypassed (jumpered over) in order to make sure the Ramtron part is supplied a full 5 volts.
Ca se confirme sur pinside
When using the 5v DIP parts the 1N5817 "blocking diode" needs to be jumpered out so the IC gets the full 5v. This diode is D23 on Data East games and D1 on Williams Sys11 games. On WPC/Stern I'm sure there are similar diodes. The 6264 adapters don't need to have the diode jumpered out since the SOIC part used on the adapter has a wider operating voltage range.
Du coup quand on utilise la puce seule, faut "bypasser" la diode d23. On fait comment ?
