Hello Terri,

Maybe you are not aware.

"I would like to recover the code from a previously programmed chip"

The only legal way of doing the above is with full AND express permission of the person who wrote the code WITHOUT trespassing any Intellectual Property issues if they exist for the code.

Anything short of even one of the above, amounts to theft.

I am afraid you may not get any methodologies for code extraction here, as you have defined it.
