Refurbished chip or re-labeling? I would understand in a ceramic package. When the package is more expensive than the die.

Do you have a picture of the 'original' CPU when it wasn't ground away? I'm not sure what to think of this chip: the outer plastic shell looks identical to my Siemens SAB 8088-1-P (this CPU); meaning it also has the slot on the left and the two round pieces.

Usually they just repaint them. Its not uncommon even on PDIPs for refurbishment (or if the marking got damaged)
Is it a working CPU?
Perhaps it had originally been labeled with a house # and got remarked to standard markings? Or was a higher speed device that didnt pass well enough and got down rated?
