Eddie Willers Member E Join Date May 2002 Location Grand Central Station Posts 615 Aug 14, 2007 #2 The PLC-5 "Enhanced" processors (includes the 5/20, /40, /80) have a hinged door on the front of the controller that holds the memory module. The memory module sticks out a bit from that door so it's easy to see.
