I noticed the Microchip ICD specifies 9 volts to power it. I also noticed that right next to the power jack, however, is a 7805 regulator, so I began to wonder if I could run it off a standard 12 volt supply (I've been using a 9 volt battery). Checking the schematic, I see that 9 volts was indeed drawn off before the regulator, but I can't find anywhere on the set of schematics that actually uses this voltage level. Has anyone tried running an ICD from a standard 12-13 volt supply? John Hansen
