Nice to hear, that you want to save all Zaccaria related datas.

I have some of your undumped pcbs, my programmer can't read the 2706 eproms though, I will check if I can help.
At the moment, I have 3 Zaccaria Dribbling pcbs, a pcb that looks like a Zaccaria made Vanguard, a Space Pirate, a Phoenix with the original Zaccaria bootleg pcb and a Pacman/Puckman/Hangly Man, that also made by Zaccaria.
