[QUOTE="nobbly, post: 6838, member: 175033"] Could be one of serveral things that are wrong. Programming software settings might not be correct. Have you tried Piccard Writer. you can download it here: http://mitglied.lycos.de/Solo0077/GW/GW67gfhdf5r67trjtre7ghfgf54r6zerth56trhfgghrfhrrztrh.htm If your using IC-Prog Try using the options for inverting MCLR and VCC It's also possible that your computers com port is unhappy: Sometimes modem software uses "Virtual modem" drivers for the com port You could try using "PIX" a dos based software. Boot your computer with a win 95,98 boot disk. You can donload it here : http://www.geocities.com/hsiliev/sat.html PIX is more reliable than IC-Prog or PICPROG. If the cards are 16F84 (not 16C84)some might fail while others will work fine Also, if you can try your programmer on a different computer to see if it's the computer or the programmer at fault.
