           - PLDs are in the JEDEC format
           - PLD checksums are not the file checksums

         * - Custom ROMs have part numbers LH53(A)(B), where:
             A is the third digit of the ROM type number
             B is the ROM ID (File ID).         

             The last three digits of the ROM type number are
             replaced with the ROM ID. Eg. LH538K30 labelled ROM
