Hi Colin, Download the ICD 2 poster (DS51265C): http://www.microchip.com/1010/pline/tools/picmicro/icds/icd2/10013/ This will give you a different perspective than MPLAB's online help ICD 2 pinout. (The pinouts are correct in both Microchip documents) Best regards, Ken Pergola P.S. -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
