Hi, i tried them as 27c400 but i keep getting an error about bad pin Zif18 Pin 30. I can blank check, read and write them fine with my GQ4X programmer. The adapter is fine with an actual 27c400

Never mind, i jumped pins 11 and 30 (both VSS in the datasheet) and XGPro blank checked, wrote and verified the chip fine
