The resistor values were shown on the page http://www.piclist.com/freeicd though I can't seem to get to that page now. They are also shown in the latest MPLAB-ICD users guide you can download from the Microchip web site - except that R21 is shown incorrectly as 100R when it should be 100k. The new resistor values are: R5 now 330R (was 680R) R21 now 100k (was 10k) R22 now 10k (was 1k) Brian Gregory. briang@cix.co.uk
