well, well, well...

I think it is now necessary to summarize the findings of this fantastic thread...

I think everybody here is interested in Vmodding the ti4200, but the procedure is still not clear.

I'll try to summarize it and if I got it wrong or if my english is crap, please correct me! Bear also in mind that I don't know anything about electrical and electronic parts...

1) we all need to buy two 5K POT and some wire...
2a) the points to be used on the POT are the central one and one of the other two. we sold some wire on these 2 points.
2b) we should set them @ 5k using the voltmeter

3) we should take off the card from the PC
4) we should measure the values of the SC chips resistance using the voltmeter on pin 11 and ground
5) we should measure the voltages using the voltmeter on the "round things" reported in the pictures above

6) we should solder the wires of the POT to pin 11 and ground on each of the 2 chips.
7) we measure again the voltage.
8) we go up with the voltage using the pot till when we are satisfied.

now, it is VERY inportant, for a complete ignorant like me, to know if each measurement can be done with the pc on or it should be off....
please correct me if i am wrong!
