Happened to be digging around in some of my old chip collections and I found a MOS Technology 4040 chip. I don't remember what it's used for and a google search came up with nothing. Any suggestions on what this chip is? I also would be happy to help identify any other chips that you need identified. Pic Related.

It was the fourth result in a google search, the first was your thread.
Then from the page which listed a different mos chip, I went to MOS category in wikipedia.

Seems to be commodore 64.
