I am having trouble reading one of my 27c512 compatible chips with my programmer. The programmer will read the chip, but the saved bin file is entirely off and unusable. I'm pulling my hair out trying to figure out why this is happening without any success.

To give you some more details, the chip is an eprom chip used in my car. I have several different chips and I'm able to read them all with my willem programmer with the exception of this one chip. This chip is not corrupted as it works perfectly in the car.

When I try to read the chip with my programmer, the hex codes in the bin appear entirely incorrect. For example, a blank line in the binary shows up as:

FF 77 EB 63 BE 36 AA 22 DD 55 C9 41 9C 14 88 00

instead of:

FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF

Any ideas and/or help would be greatly appreciated!!!
