Chip not on the list?
The table only holds parts we have already published, a fraction of the 5000+ models in the database. Most unlisted markings are still workable, especially older 8-bit parts and anything in a DIP, SOP or QFP package. Send the marking and you get a yes or no with a price.

Photograph the top of the chip. If the marking is worn we can often still identify it from the package and the board.
