Thanks for the help Kurt! Perhaps I can clarify what I'm looking for.
I found this picture of a Congo boardset from a completed Ebay auction
after I posted last night:

http://cgi.ebay.com/aw-cgi/eBayISAPI.dll?ViewItem&item=433696872&ed=968806374

The chip I am referring to is on the left hand board in the picture (the
board with the heatsink labeled "Volume Control"). It is the second
chip up from the bottom right hand corner of the board. It is the only
socketed 40 pin chip on the entire board. That socket appears to be
stenciled "U29" on my board, but I could be mistaken.
