I have a M27C512 chip that I need to copy, however, it seems as though
there is a copy protection on the chip. Is there an IC programmer that
lets you make a 1 to 1 copy of a protect IC chip.

Every time I try to do a read from the chip, all it reads is FF FF FF.
Does anyone know how to get around this.

Thanks

No, what that means is one of two things: A, your reader is broken or
B, the EPROM has already been erased, and its contents are lost to the
bit bucket.

It shouldn't take long to troubleshoot your reader.

Sorry,
