you can use use Teensy to read the NANDs. The project is located at github.com /Effleurage/NORway-and-NANDway.
The NANDs on the mobo can't be powered from the 3.3v regulator. The current demand is too high (the mobo demands 1.8A and Teensy powered from USB can supply only 500mA).
The NANDs on the mobo can be powered from external source (like from the progskeet or from ATX power supply). Make sure that all grounds are firm and connected together - this will improve the reading dramatically.
With the NANDs on the motherboard you can discard WP# and RYBY# (no wiring required).
I've added support to Differential write - so once you have a good read and patch it using flow rebuilder - you can try it out and save yourself a lot of time.
Teensy can be still be driven from the 3.3v regulator (but not directly from the USB 5v). Just again - make sure that the usb ground is firmly connected to the ps3 mobo ground.
make sure you have no shorts and that each wire is connected and have no resistance (test it with a multimeter)
I hope it helps. good luck!
