I've constructed the PIC programmer as described on the following web page: http://www.ebar.dtu.dk/~c888600/files/newpics.htm Unfortunately, there is not a lot of documentation on the page or with the software (I'm not even sure exactly what software to use with it.) I'm trying to program a 16C71 for a class project and any input would be most appreciated. You would think with the thousands of dollars they spend in this lab, they'd buy us a PIC programmer... :] -Vincent Deno
