Good, that info should narrow the search down a bit. The info on the top is 61L23 RCA 8715 (which I assume 8715 is the date code) and on the bottom are 4ZLRC on one line and below that is P6502 in the standard 8 pin DIP. wa9zzu

Tedd, Check out this Google search, http://www.alldatasheet.com/view.jsp?Searchword=61L23 . It should have all you need, if not there is a lot of other sites ID'ing the chips.
