hi, today the adp 054 adapter arrived and i start to play with the 27c1024, I had a memory to read and I put it in to see if everything worked well. I read the memory 3 times and had 3 different files, there are 2 wrong bytes in the address 1770. What should I check to get the file right?
Image Insert:
202741 bytes |

Does the 2 27C1024 have the problem at the same address? |

You can compare 2 or more reads and edit the bad values. |

In the USBProg software select "Device" in the menu then "User Folder" and the "devices.txt" should be there.

Don't think it should be a problem since the software sees it.
5V is the default voltage. |

5.5V first, if it still fails then 6.2V, after that 6.5V. |
