| Comments | The IC reads "813BS" and not "8138S" (SN74159N date codes end "BS" or "DS" and have three or four digits); therefore this is not a pre-SKCL Alps mount example, nor does it contradict all other evidence of 12K to 56AAA PCB code transition); the chip itself is a decoder/demultiplexer, not a microcontroller |
