Yes. You just need to add a resistor. There used to instructions for doing this on the Carnetix site.
Is there any way to mod a p1900 that I bought just before the intel minis came out to work with an intel mini. Right now I'm running a ppc but was thinking about upgrading to an intel, and whether or not I have to buy a new power supply too will play a big part in the decision.
Can be a bit tricky.
I destroyed the onboard resistor and used a 33k one on the back of the board, although it can be in line with the isence wire as long as it connects to the black earth wire.
