Are you looking for the diagrams for a keyboard wedge (to connect a scanner device to a computer via the keyboard port? Or one that connects to the LPT or serial ports and the decoding is handled by software on the PC? If you are looking for information on the latter, go to Radio Shack and pick up a CueCat

CueCat are barcode decoders that are passed out with their catalogs.
