Daniele Fua is in the Dept. of Physics at Sapienza University of Rome, and he has written notes about upgrading the Neco Drive unit. He kindly sent me an updated version of his notes, which I have now used to replace those that were previously posted on our Equipment Manuals page.
Thanks Daniel for providing us these notes – I know it has already helped more than one Nic 38 owner.
