I reset the GQ and this time I do an ID first which gives STElectronics M27C1000 Hmm I think and try to read again with the same result as before. So I set the device to M27C1000 and try to read again - same result - C3 in all places. I have tried both chips which are PLCC32 and keep getting the same C3 result no matter what. The only thing that seems to work is doing the ID after resetting the HW and SW. I have lightly sanded the legs on the chip too and I am using the PLCC32 adapted in the socket. Many thsnks !
