Set the yearRange option. Add yearRange: "1980:2014", (or whatever start and end years you need):

 $("#txtbox").datepicker({
     prevText: "",
     nextText: "",
     changeMonth: true,
     changeYear: true,
     showButtonPanel: true,
     dateFormat: 'mm/yy',
     yearRange: "1980:2014",
     onClose: function (dateText, inst) {
         var month = $("#ui-datepicker-div .ui-datepicker-month :selected").val();
         var year = $("#ui-datepicker-div .ui-datepicker-year :selected").val();
         $(this).datepicker('setDate', new Date(year, month, 1));
     }
 });
