I just had to buy a set of EPROMs for a customers Fadal machine. They were 800.00 I bought the EPROM reader and can now duplicate any Fadal Chip. I am new to this, and i am sure there will be a learning process, but I should be able to duplicate any chip set. I have several Yasnac LX-1 main boards with corrupted proms, I am hoping to soon be able to repair these. As these machines get older, they are going to be harder to repair, and more expensive to repair. Any help I can provide I will.
