I've got a 27C512 EPROM from a prototype game that unfortunately is only giving a partial dump, I've heard it appears one address line isn't working, apparently at xxxxx1xxxxxxxxxx = 0xFF
Aside from trying multiple dumps on different programmers and cleaning the legs, are there any tricks people know of that might get me a complete and good read? It only needs to work once!  We're pretty much screwed if we can't get it to dump as there's no other source for that ROM.
