So, this brings up the question, if there is any
real advantage to buying a Nikon digital so that I can
use my old fixed manual focus sharp lenses, if I can't
focus them.


You should be aware that your manual focus lenses will mount to the
D70, but the camera's metering will not work. You will either have to
use a hand held meter and set the exposure manually, or use trial and
error, informed by the histogram.
