Thanks DT, I was afraid of that. Yep all of them have dead battery acid or corrosion on the boards,LCD screen,etc. I am just selling the part off them now for salvage and getting my money back that way. One thing I hate is batteries in a keyboard! Every portable I ever bought used in the fleamarket or ebay has that problem. People think batteries last forever and can be left in. No I say! Shame about the CZ101s and CZ1000s then. I will keep buying pig in a pokes till I get parts to make a good one lol!
