Archive Parts List (APL) is designed to work as an extension of Cummins Electronic Parts Catalog (CEPC) by providing part number information for an additional 2 million engines built from 1960 to 1984. APL combines the parts information from Cummins microfiche system with build data from the engine history file to provide the most complete information available for these vintage engines. A part number supersession file is also included on each of the three ROMs. CEPC must be installed to use this product. APL is updated annually.
