I turned on the firewire extensions and now NS works.
Early tests using the Stouffer gray scale show exceptional linearity down
to a OD of 2.25, then an abrupt flattening of the curve above that. Using
OD axis, the sensitivity is actually highest between 1.6 and 2.25. It
appears the sensor or the A/D has a negative offset. Similar results are
obtained with Vuescan and NikonScan 3.0.
