This is all to weird, plugged it in, Program was on the wrong chip, error'd, changed its mode to 95040, Read/dumped the chip, it was junk, Programmed it with the correct bin and it programed without anything weird.

Is erasing the chip or anything needed prior? or was this ( Somewhat dumb ) move a stroke of luck?

Generally if you aren't getting a good read you shouldn't try writing to it. Did you read it to verify your write was successful?

Quite a few times now, and each time its been 100% correct.

I feel as though the error of having the programmer on 27C256 while trying to read the 95040 caused some corruption.

i can continue to check, But its checked out Four times now on two separate occasions.

I have seen cases of corrupting the data on eproms when trying to read them using the wrong chip type.
