Please ensure that external protection for MCLR is in place (Press the Help button for an example circuit or use AC164112 available from microchipDIRECT.com)" A little searching finds:=20 http://www.microchip.com/forums/tm.aspx?m=3D409832 Yep=85 the ICD2 will kil= l a 14k22 and also: PIC16F727=A0 Family=20 PIC16F1937 Family=20 PIC18F14K22 Family=20 PIC18F14K50 Family=20 PIC18F46K20 Family=20 PIC24F16KA102 Family so I have to modify the board I'm using or put out another $10 to make it compatible=20 http://www.microchipdirect.com/productsearch.aspx?Keywords=3DAC164112 http://parts.digikey.com/1/parts/1583015-voltage-limiter-mplab-icd2-vpp-ac1= 6 4112.html Wouldn't it have been nice if they had told me that when I ordered the stupid AC244033 adapter?
