Thanks Nino and Owen. I had a play of a Zaccaria Robot recently and was pretty amazed by the game. During the game you have 5 pop target which rise from the centre of the playfield and then you need to hit each target to lower it.
I would be glad to help any other collectors with faulty boards for Zaccaria or other games. I am looking at advertising a pinball board repair service in the near future.
regards Derek
