I bought a bunch of these years ago, and no matter what machine I try to use them in, they do not work. They cause random coil locks. Sometimes the machine will freak out for no reason. Settings change to random things. Last night I had it lock on about 4 or 5 coils randomly. Would lock and hold for a couple of seconds, then release. Others were locked on right away. Almost burned up 5 coils. Luckily I was paying attention.

these are 100% useless for Zaccaria.

I bought a bunch of Brinks chips back in the day. They work great, but you must have both ram chips socketed, as it uses both spots. But they are reliable. Pins are very fragile and it's very hard to remove them without breaking off a pin.

Looks like Pinball solutions has a one socket option now. I have not used these yet.

yes, brinks setup is duel and uses both sockets. I have had 1 bad one that will not hold settings, but the rest I have installed have worked flawless. Have 3 that have broken pins, because they are very fragile and do not like to come back out once installed.

I missed that you retracted the Zaccaria compatibility. I did buy these quite awhile ago. Just finally got around to trying to use them.
