I am having a problem writing this M27C1024 chips. Bought 10 NEW EMPTY ones and I can read the original with the ADP-054. When I try to flash the empty ones I always get error like : Write failed, Address=0x000200, Buffer=0xB1 Device=0xFF Write failed Tried another chip, same error. Cleaned all contacts. Tested programmer for voltage etc. And as I said, I can read the original just fine. Blank check does not help for s%%% as it tells me chip is blank even without the adapter attached to the programmer. Can see many people had problems with this chips but nobody posted a solution. Any help appreciated. [/quote]    Insert an Image File Check here to include your profile signature.
